security fix for sudo
Module Name: pkgsrc
Committed By: cube
Date: Fri Nov 26 16:23:57 UTC 2004
Modified Files:
pkgsrc/security/sudo: Makefile distinfo
Log Message:
sudo is nominated for crapware of the year. Now at version 1.6.8pl4!
Just as for pl2, changes are about environment sanitizing, meaning
there are possible security issues with current versions.
Changes:
550) The CDPATH variable is now stripped from the environment passed
to the program to be executed.
551) Fix temp file generation on systems where the _PATH_VARTMP macro
lacks a trailing slash.
552) The KRB5CCNAME environment variable is preserved during sudo
execution for password lookups that use GSSAPI.

security fix for sudo
Module Name: pkgsrc
Committed By: cube
Date: Fri Nov 12 16:47:31 UTC 2004
Modified Files:
pkgsrc/security/sudo: Makefile PLIST.NetBSD PLIST.SunOS distinfo
Log Message:
Update to version 1.6.8pl2. Fixes a security flaw for the sad people using
bash-as-sh (and people allowing bash scripts to be run through sudo). The
user could override commands by functions of her own.
ChangeLog:
549) Bash exported functions and the CDPATH variable are now stripped from
the environment passed to the program to be executed.

Changes since 0.0.8:
* Changes in 0.1.4 (released 2004-08-08)
** Revamp of gnulib compatibility files.
** More translations.
German (by Roland Illig), Basque (by Mikel Olasagasti), French (by
Michel Robitaille), Irish (by Kevin Patrick Scannell), Dutch (by Elros
Cyriatan), Polish (by Jakub Bogusz), Romanian (by Laurentiu Buzdugan),
and Serbian (by Aleksandar Jelenak).
* Changes in 0.1.3 (released 2004-08-04)
** Command line tool support IPv6 (and other protocol families).
Requires that your system has `getaddrinfo'.
** Command line behaviour for gsasl tool improved.
The --client and --imap parameters are now the default. The --connect
host and port can now be specified directly. If --authentication-id
is not specified, the username of the user invoking gsasl is used
(i.e., getpwuid(getuid)->pw_name). Alltogether, this allows simple
usage, as in `gsasl mail.example.com' to connect, via IMAP, to
mail.example.com.
* Changes in 0.1.2 (released 2004-07-16)
** The SMTP mode in `gsasl' should now work.
** Cross compile builds should work.
It should work for any sane cross compile target, but the only tested
platform is uClibc/uClinux on Motorola Coldfire.
** The GNU Readline library is used to read data, if available.
** Passwords read from stdin are not echoed to the terminal.
* Changes in 0.1.1 (released 2004-06-26)
** In the command line client, the default quality of protection is now none.
* Changes in 0.1.0 (released 2004-04-16)
** The library re-licensed to LGPL and distributed as a separate package.
This means a fork of this NEWS file, all the entries below relate to
the combined work of earlier versions. New entries above does not
document user visible changes for the library ("libgsasl"), for that
see NEWS in the lib/ sub-directory, which is also distributed as a
stand-alone package.
* Changes in 0.0.14 (released 2004-01-22)
** Moved all mechanism specific code into sub-directories of lib/.
Each backend is built into its own library (e.g., libgsasl-plain.so),
to facilitate future possible use of dlopen to dynamically load
backends.
** Moved compatibility files (getopt*) to gl/, and added more (strdup*).
* Changes in 0.0.13 (released 2004-01-17)
** Nettle (the crypto functionality, crypto/) has been updated.
This fixes two portability issues, the new code should work on
platforms that doesn't have inttypes.h and alloca.
* Changes in 0.0.12 (released 2004-01-15)
** Protocol line parser in 'gsasl' tool more reliable.
Earlier it assumed two lines were sent in one packet in one place, and
sent as two packets in another place.
** Various bugfixes.
* Changes in 0.0.11 (released 2004-01-06)
** The client part of CRAM-MD5 now uses SASLprep instead of NFKC.
This aligns with draft-ietf-sasl-crammd5-01.
** The CRAM-MD5 challenge string now conform to the proper syntax.
** The string preparation (SASLprep and trace) functions now work correctly.
** DocBook manuals no longer included.
The reason is that recent DocBook tools from the distribution I use
(Debian) fails with an error. DocBook manuals may be included in the
future, if I can get the tools to work.
** API and ABI modifications.
GSASL_SASLPREP_ERROR: ADD.
* Changes in 0.0.10 (released 2003-11-22)
** The CRAM-MD5 server now reject invalid passwords.
The logic flaw was introduced in 0.0.9, after blindly making code
changes to shut up valgrind just before the release.
** Various build improvements.
Pkg-config is no longer needed. GTK-DOC is only used if present.
* Changes in 0.0.9 (released 2003-11-21)
** Command line client can talk to SMTP servers with --smtp.
** DocBook manuals in XML, PDF, PostScript, ASCII and HTML formats included.
** Token parser in DIGEST-MD5 fixed, improve interoperability of DIGEST-MD5.
** Libgcrypt >= 1.1.42 is used if available (for CRAM-MD5 and DIGEST-MD5).
The previous libgcrypt API is no longer supported.
** CRAM-MD5 and DIGEST-MD5 no longer require libgcrypt (but can still use it).
If libgcrypt 1.1.42 or later is not found, it uses a minimalistic
cryptographic library based on Nettle, from crypto/. Currently only
MD5 and HMAC-MD5 is needed, making a dependence on libgcrypt overkill.
** Listing supported server mechanisms with gsasl_server_mechlist work.
** Autoconf 2.59, Automake 1.8 beta, Libtool CVS used.
** Source code for each SASL mechanism moved to its own sub-directory in lib/.
** The command line interface now uses getopt instead of argp.
The reason is portability, this also means we no longer use gnulib.
** API and ABI modifications.

http://www.sudo.ws/sudo/alerts/sudoedit.html
Major changes since Sudo 1.6.8:
o Sudoedit now re-opens the temp file as the invoking user
and will only open regular files.
o Better detection of unchanged files in sudoedit.
o The path to ldap.conf is now configurable.
o Added SSL tls_* certificate checking options when using LDAP.
o The sample pam config file has been updated.

NetBSD-1.6.2_STABLE. Gets rid of a parse error when only one
argument is given to HDN_WARN, which leaves us with "fprintf(fp, arg, )".
This may be a failure of the compiler on this platform to properly
do varargs macros, but the changes are noops and gets it building there.

-lreadline also needs either -ltermcap, -lcurses, -lncurses in the link
command to resolve all symbols used in the readline library. Cause one
of these libraries to automatically be added whenever "-lreadline"
appears on the command line. This is a generalization of the change in
revision 1.6 to work on more operating systems.

dependencies. This fixes link failures when the Heimdal dependency
is satisfied by the package rather than the builtin Heimdal. Pointed
out by Mark Davies in private email.
I've intentionally left out including readline/buildlink3.mk. Although
it is used by libsl.* and libss.*, those libraries are not actually
critical or used by other packages that depend on Heimdal for Kerberos
functionality.

* Added new "IdentitiesOnly" option to ssh(1), which specifies that it should
use keys specified in ssh_config, rather than any keys in ssh-agent(1)
* Make sshd(8) re-execute itself on accepting a new connection. This security
measure ensures that all execute-time randomisations are reapplied for each
connection rather than once, for the master process' lifetime. This includes
mmap and malloc mappings, shared library addressing, shared library mapping
order, ProPolice and StackGhost cookies on systems that support such things
* Add strict permission and ownership checks to programs reading ~/.ssh/config
NB ssh(1) will now exit instead of trying to process a config with poor
ownership or permissions
* Implemented the ability to pass selected environment variables between the
client and the server. See "AcceptEnv" in sshd_config(5) and "SendEnv" in
ssh_config(5) for details
* Added a "MaxAuthTries" option to sshd(8), allowing control over the maximum
number of authentication attempts permitted per connection
* Added support for cancellation of active remote port forwarding sessions.
This may be performed using the ~C escape character, see "Escape Characters"
in ssh(1) for details
* Many sftp(1) interface improvements, including greatly enhanced "ls" support
and the ability to cancel active transfers using SIGINT (^C)
* Implement session multiplexing: a single ssh(1) connection can now carry
multiple login/command/file transfer sessions. Refer to the "ControlMaster"
and "ControlPath" options in ssh_config(5) for more information
* The sftp-server has improved support for non-POSIX filesystems (e.g. FAT)
* Portable OpenSSH: Re-introduce support for PAM password authentication, in
addition to the keyboard-interactive driver. PAM password authentication
is less flexible, and doesn't support pre-authentication password expiry but
runs in-process so Kerberos tokens, etc are retained
* Improved and more extensive regression tests
* Many bugfixes and small improvements

- SECURITY: Don't try to free() uninitialised variables in DSS verification
code. Thanks to Arne Bernin for pointing out this bug. This is possibly
exploitable, all users with DSS and pubkey-auth compiled in are advised to
upgrade.
- Clean up agent forwarding socket files correctly, patch from Gerrit Pape.
- Don't go into an infinite loop when portforwarding to servers which don't
send any initial data/banner. Patch from Nikola Vladov
- Fix for network vs. host byte order in logging remote TCP ports, also
from Gerrit Pape.
- Initialise many pointers to NULL, for general safety. Also checked cleanup
code for mp_ints (related to security issues above).

which are the full option names used to set rpath directives for the
linker and the compiler, respectively. In places were we are invoking
the linker, use "${LINKER_RPATH_FLAG} <path>", where the space is
inserted in case the flag is a word, e.g. -rpath. The default values
of *_RPATH_FLAG are set by the compiler/*.mk files, depending on the
compiler that you use. They may be overridden on a ${OPSYS}-specific
basis by setting _OPSYS_LINKER_RPATH_FLAG and _OPSYS_COMPILER_RPATH_FLAG,
respectively. Garbage-collect _OPSYS_RPATH_NAME and _COMPILER_LD_FLAG.

adds two new options, ldap and pam.
Changes:
* Sudo now supports storing sudoers info in LDAP (optionally using TLS).
* There is a new -e option to edit files the with uid of the invoking
user. This makes it possible to give users to ability to safely edit
files without the possibility of editing other files or running commands
as the target user. If sudo is run as "sudoedit" the -e flag is implied.
* A new tag, NOEXEC, will prevent a dynamically-linked program being run
by sudo from executing another program (think shell escapes). Because
this uses LD_PRELOAD it has no effect on static binaries.
* A uid specified in sudoers now matches the user specified by the -u flag
even if the -u flag specified a name, not a uid.
* Added a -i option to simulate an initial login similar to "su -".
* If sudo is used to run as root shell, further sudo commands will be logged
as run by the user specified by the SUDO_USER environment variable. In -e
mode (sudoedit), SUDO_USER is used to determine what user to run the editor
when the real uid is 0.
* The sudoers file is now parsed as the runas user in all cases instead of
root. This fixes some issues with running NFS-mounted commands.
* If the target user == invoking user a password is no longer required.
* Sudo now produces a sensible error message when the targetpw Defaults option
is set and a non-existent uid is specified via the -u option.
* A negated user/uid in a runas list is now treated the same as a negated
command and overrides a previously allowed entry.
* PAM support now uses Use pam_acct_mgmt() to check for disabled accounts.
* Added a check in visudo for runas_default being used before it was set.
* Fixed several issues when closing all open descriptors. Sudo now uses
closefrom() if it exists, otherwise it uses /proc/$$/fd if that exists
with a fallback of closing all possible descriptors.
* Quoting globbing characters with a backslash now works as documented.
* Fixed a problem on FreeBSD (and perhaps others) when the user is only
listed in NIS (not master.passwd) and netgroups are used in the
master.passwd file.
* The username in a log entry is no longer truncated at 8 characters.
* Added a "sudo_lecture" option that can point to a file containing a
custom lecture.
* The timeout for password reading is now done via alarm(), not select().
* /tmp/.odus is no longer used for timestamps by default.
* Sudo now works on the nsr-tandem-nsk platform.
* Fixed the --with-stow configure option.
* TIS fwtk authentication now supports fwtk 2.0 and higher.
* Added Stan Lee / Uncle Ben quote to the lecture from RedHat.
* Added the --with-pc-insults configure to replace politically incorrect
insults with other ones.

into the bsd.options.mk framework. Instead of appending to
${PKG_OPTIONS_VAR}, it appends to PKG_DEFAULT_OPTIONS. This causes
the default options to be the union of PKG_DEFAULT_OPTIONS and any
old USE_* and FOO_USE_* settings.
This fixes PR pkg/26590.

Noteworthy changes in version 0.9.0 (unreleased)
------------------------------------------------
* The type gpgme_key_t has now a new field keylist_mode that contains
the keylist mode that was active at the time the key was retrieved.
* The type gpgme_decrypt_result_t has a new field "wrong_key_usage"
that contains a flag indicating that the key should not have been
used for encryption.
* Verifying a signature of a revoked key gives the correct result now
(GPG_ERR_CERT_REVOKED error code).
* Clarified that the error code GPG_ERR_NO_DATA from the decrypt &
verify operations still allows you to look at the signature
verification result.
* Clarified that patterns in keylisting operations have an upper
limit, and thus are not suited to list many keys at once by their
fingerprint. Also improve the error message if the pattern is too
long for the CMS protocol to handle.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gpgme_key_t EXTENDED: New field keylist_mode.
gpgme_decrypt_result_t EXTENDED: New field wrong_key_usage.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Set the 0.9.0 versions as BUILDLINK_DEPENDS in the buildlink3.mk for the
library major version changes.

Noteworthy changes in version 0.4.7 (2004-04-29)
------------------------------------------------
* Correctly initialize the fields expired, revoked, invalid, and
disabled in the gpgme_key_t structures.
* A bug fix: The flag wrong_key_usage of gpgme_signature_t was
accidently of type int instead unsigned int.
Noteworthy changes in version 0.4.6 (2004-04-06)
------------------------------------------------
* Bug fixes
Noteworthy changes in version 0.4.5 (2004-03-07)
------------------------------------------------
* GPGME is now compiled with LFS (large file support) by default.
* New key listing mode GPGME_KEYLIST_MODE_VALIDATE for validation of
the listed keys.
* New interface gpgme_cancel() that can be used to cancel
asynchronous operations.
Noteworthy changes in version 0.4.4 (2004-01-12)
------------------------------------------------
* The member "class" in gpgme_key_sig_t and gpgme_new_signature_t has
been renamed to "sig_class", to avoid clash with C++ compilers. In
the C API, the old name "class" has been preserved for backwards
compatibility, but is deprecated.
