   Log Message:
   Security fix for SA17062:

   "A vulnerability in UW-imapd can be exploited by malicious users to
    cause a DoS (Denial of Service) or compromise a vulnerable system.

    The vulnerability is caused due to a boundary error in the
    "mail_valid_net_parse_work()" function when copying the user supplied
    mailbox name to a stack buffer. This can be exploited to cause a
    stack-based buffer overflow via a specially crafted mailbox name that
    contains an single opening double-quote character, without the
    corresponding closing double-quote.

    Successful exploitation allows arbitrary code execution, but requires
    valid credentials on the IMAP server."

    valid credentials on the IMAP server."
