    Debian Security Advisory DSA 386-1 security@debian.org

    Package : libmailtools-perl
    Vulnerability : input validation
    Problem-Type : local, remote
    Debian-specific: no
    CVE Ids : CAN-2002-1271

    The SuSE security team discovered during an audit that the
    Mail::Mailer module, a Perl module used for sending email, whereby
    potentially untrusted input is passed to a program such as mailx,
    which may interpret certain escape sequences as commands to be
    executed.

    This bug has been fixed by removing support for programs such as mailx
    as a transport for sending mail. Instead, alternative mechanisms are
    used.

    For the stable distribution (woody) this problem has been fixed in
    version 1.44-1woody1.

    For the unstable distribution (sid) this problem will be fixed soon.

    We recommend that you update your libmailtools-perl package.
