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.
