Debian DSA-1155-2 : sendmail - programming error

medium Nessus Plugin ID 22697
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

It turned out that the sendmail binary depends on libsasl2 (>= 2.1.19.dfsg1) which is neither available in the stable nor in the security archive. This version is scheduled for the inclusion in the next update of the stable release, though.

You'll have to download the referenced file for your architecture from below and install it with dpkg -i.

As an alternative, temporarily adding the following line to /etc/apt/sources.list will mitigate the problem as well :

deb http://ftp.debian.de/debian stable-proposed-updates main

Here is the original security advisory for completeness :

Frank Sheiness discovered that a MIME conversion routine in sendmail, a powerful, efficient, and scalable mail transport agent, could be tricked by a specially crafted mail to perform an endless recursion.

Solution

Upgrade the sendmail package.

For the stable distribution (sarge) this problem has been fixed in version 8.13.4-3sarge2.
