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.
