Debian Security Advisory

DSA-386-1 libmailtools-perl -- input validation bug

Date Reported:

18 Sep 2003

Affected Packages:

libmailtools-perl

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CAN-2002-1271.

More information:

The SuSE security team discovered during an audit a bug in Mail::Mailer, 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.

Fixed in:

Debian GNU/Linux 3.0 (woody)
