Debian DLA-2005-1 : tnef security update

medium Nessus Plugin ID 131430

Language:

Synopsis

The remote Debian host is missing a security update.

Description

In tnef, an attacker may be able to write to the victim's .ssh/authorized_keys file via an e-mail message with a crafted winmail.dat application/ms-tnef attachment, because of a heap-based buffer over-read involving strdup.

For Debian 8 'Jessie', this problem has been fixed in version 1.4.9-1+deb8u4.

We recommend that you upgrade your tnef packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected tnef package.
