Debian DSA-3869-1 : tnef - security update

critical Nessus Plugin ID 100560

Language:

Synopsis

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

Description

It was discovered that tnef, a tool used to unpack MIME attachments of type 'application/ms-tnef', did not correctly validate its input. An attacker could exploit this by tricking a user into opening a malicious attachment, which would result in a denial-of-service by application crash.

Solution

Upgrade the tnef packages.

For the stable distribution (jessie), this problem has been fixed in version 1.4.9-1+deb8u3.
