(UW IMAP toolkit: Multiple vulnerabilities)

    Multiple vulnerabilities were found in the UW IMAP toolkit:
    Aron Andersson and Jan Sahlin of Bitsec reported boundary errors in
    the 'tmail' and 'dmail' utilities when processing overly long mailbox
    names, leading to stack-based buffer overflows (CVE-2008-5005).
    An error in smtp.c in the c-client library was found, leading to a
    NULL pointer dereference vulnerability (CVE-2008-5006).
    Ludwig
    Nussel reported an off-by-one error in the rfc822_output_char()
    function in the RFC822BUFFER routines in the c-client library, as used
    by the UW IMAP toolkit (CVE-2008-5514).
  
Impact :

    A remote attacker could send an e-mail to a destination mailbox name
    composed of a username and '+' character followed by a long string,
    possibly leading to the execution of arbitrary code. A local attacker
    could gain privileges by specifying a long folder extension argument to
    the tmail or dmail program. Furthermore, a remote attacker could send a
    specially crafted mail message to the UW IMAP toolkit or another daemon
    using the c-client library, leading to a Denial of Service. A remote
    SMTP server could respond to the QUIT command with a close of the TCP
    connection instead of the expected 221 response code, possibly leading
    to a Denial of Service.
  
Workaround :

    There is no known workaround at this time."
