Multiple X servers fail to properly allocate memory for large pixmaps

Vulnerability Note VU#102441

Original Release Date: 2005-09-13 | Last Revised: 2005-11-03

Overview

Multiple X Window System servers contain a pixmap memory allocation flaw that may allow local users to execute code with elevated privileges.

Description

Multiple X Window System server applications share code that may contain a flaw in the memory allocation for large pixmaps. The affected products include the X.Org and XFree86 X server applications, possibly among others.

An integer overflow condition may result in a memory allocation request returning an allocated region that is incorrectly sized. The client may then be able to use the XDrawPoint() and XGetImage() functions to read and write to arbitrary locations in the X server's address space.

Impact

A malicious local authenticated attacker may be able to execute arbitrary code with the privileges of the X server.

Solution

Contact your vendor for updates, fixes, and workarounds.
