Mandriva Linux Security Update Advisory - A vulnerability was discovered in the pixmap allocation handling of the X server that can lead to local privilege escalation. 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, leading to a buffer overflow which could then be exploited to execute arbitrary code with full root privileges.
