Debian DSA-3798-1 : tnef - security update

high Nessus Plugin ID 97474

Language:

Synopsis

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

Description

Eric Sesterhenn, from X41 D-Sec GmbH, discovered several vulnerabilities in tnef, a tool used to unpack MIME attachments of type 'application/ms-tnef'. Multiple heap overflows, type confusions and out of bound reads and writes could be exploited by tricking a user into opening a malicious attachment. This would result in denial of service via application crash, or potential arbitrary code execution.

Solution

Upgrade the tnef packages.

For the stable distribution (jessie), these problems have been fixed in version 1.4.9-1+deb8u1.
