Debian Security Advisory DSA 386-1 security@debian.org
http://www.debian.org/security/ Matt Zimmerman
September 18th, 2003 http://www.debian.org/security/faq

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.
