This can lead to either a +crash or potentially a heap-based buffer overflow crash. No known +exploits exist, but main concern is where an untrusted user who +possesses privileged access in a guest Xen environment could corrupt a +filesystem which is then accessed by the pygrub program, running as +root in the dom0 host environment, thus allowing the untrusted user to +gain privileged access in the host OS. Thanks to the McAfee AVERT +Research group for reporting this issue. (Addresses CVE-2007-5497.) + +Fix hueristics in blkid which could cause a disk without partitions to +be incorrectly skipped when a loopback device is present. (Addresses +Red Hat Bugzilla #400321.) + +Fix e2image so that in raw mode it does not create an image file which +is one byte too large. + +Change mke2fs's usage message so it recommends the preferred -E option +instead of the deprecated -R option. + +Enhance the blkid library so it will recognize squashfs filesystems. +(Addresses Red Hat Bugzilla #305151.) + +Enhance e2fsck so it will force the backup superblocks to be backed up +if the filesystem is consistent and key constants have been changed +(i.e., by an on-line resize) or by e2fsck in the course of its +operations. + +Enhance blkid's detection of FAT filesystems; so that USB disks with +only a single bootable partition will not get missed. + +E2fsck will no longer mark a filesystem as invalid if it has time +errors (i.e., if superblock mount time or last write time is in the +future) and the user refuses to fix the problem. + +The Ubuntu init scripts don't properly set the system time correctly +from hardware clock if the hardware clock is configured to tick local +time instead of GMT time. Work around this as best as we can by +providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can +be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu +Bug #131201.) + +Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red +Hat Bugzilla #151533.) + +Fix e2fsck so that if the superblock is corrupt, but still looks +vaguely like an ext2/3/4 superblock, that it automatically tries to +fall back to the backup superblock, instead of failing with a hard +error. + +Make the e2fsprogs program more robust so that they will not crash +when opening a corrupt filesystem where s_inode_size is zero. + +Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric +arguments are detected as such and the parse error is reported to the +user. (Addresses Debian Bug #435381.) + +Change e2fsck so it will not complain if a file has blocks reallocated +up to the next multiple of a system's page size. + +Fix bug in ext2fs_check_desc() which will cause e2fsck to complain +about (valid) filesystems where the inode table extends to the last +block of the block group. (Addresses Red Hat Bugzilla #214765.) + +Fix a bug in ext2fs_initialize() which causes mke2fs to fail while +allocating inode tables for some relatively rare odd disk sizes. +(Addresses Red Hat Bugzilla #241767.) + +Add Catalan translation and update Dutch and Swedish translations +from the Translation Project. + +Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We +still had an issue when trying to figure out whether we need to +byte-swap fast symlinks that contained extended attributes. + +Fixed spelling mistakes, typos, and otherwise clarified man pages. +(Addresses SourceForge Bug #1821333.) + + +Programmer's Notes: +------------------- + +Fix mke2fs tests to avoid needing any significant ^M (CR) characters + +Add "make check" to the RPM spec file + +Fix "make install" and 'make unstall" in misc/Makefile.in so that it +works correctly when the prefix is not the root directory. + +Fix the resize2fs tests, r_move_itable and r_resize_inode, so they +clena up after themselves by deleting the test.img temporary file +after completing the test. + +Fixed a corner case bug ext2fs_unlink() when trying to delete the +first directory entry in a directory block and the last directory +entry in the previous directory block is not in use. Fortunately +ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in +places where it is extremely unlikely to run into this corner case. + +Fix missing dependency which would cuase parallel builds to fail. +(Addresses Sourceforge Bug #1842331.) + +Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c +calling open(O_CREATE) with a missing mode parameter. + +Fix the test_ss.c in lib/ss so it can be used as an example +application program for the library as well as a regression test +suite. + +Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes +are properly passed back up through the call stack. + E2fsprogs 1.40.2 (July 12, 2007) ================================ @@ -304,7 +420,8 @@ the superblock.
