Description :

A local privilege escalation vulnerability has been discovered in the
pixmap allocation handling of the X server. By allocating a huge
pixmap, a local user could trigger an integer overflow that resulted
in a memory allocation that was too small for the requested pixmap.
This resulted in a buffer overflow which could eventually be exploited
to execute arbitrary code with full root rights.

Solution :

Upgrade to :
- lbxproxy-6.8.2-10.1 (Ubuntu 5.04)
- libdmx-dev-6.8.2-10.1 (Ubuntu 5.04)
