USN-92-1: LessTif vulnerabilities

Ubuntu Security Notice USN-92-1

7th March, 2005

lesstif1-1 vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 4.10


Several vulnerabilities have been found in the XPM image decoding
functions of the LessTif library. If an attacker tricked a user into
loading a malicious XPM image with an application that uses LessTif,
he could exploit this to execute arbitrary code in the context of the
user opening the image.

Ubuntu does not contain any server applications using LessTif, so
there is no possibility of privilege escalation.
