mlterm: Integer overflow vulnerability — GLSA 200503-13

mlterm is vulnerable to an integer overflow, which could potentially allow the execution of arbitrary code.

Affected Packages

x11-terms/mlterm on all architectures
Affected versions < 2.9.2
Unaffected versions >= 2.9.2

Background

mlterm is a multi-lingual terminal emulator.

Description

mlterm is vulnerable to an integer overflow that can be triggered by specifying a large image file as a background. This only effects users that have compiled mlterm with the 'gtk' USE flag, which enables gdk-pixbuf support.

Impact

An attacker can create a specially-crafted image file which, when used as a background by the victim, can lead to the execution of arbitrary code with the privileges of the user running mlterm.

Workaround

Re-compile mlterm without the 'gtk' USE flag.

Resolution

All mlterm users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=x11-terms/mlterm-2.9.2"
