X.Org pixmap buffer overflow
| xorg-pixmap-bo (22244) |  High Risk |
Description:
X.Org is vulnerable to a heap-based buffer overflow in the pixmap memory allocation. By sending a large pixmap, a local attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges.
Note: It is reported that XFree86 versions. 4.1.x through 4.5.x, X Windows System (X11) version 6.x as well as all versions of Avaya Modular Messaging Message Storage Server (MSS), Avaya Message Networking (all versions) and Avaya Intuity LX (all versions) are vulnerable to this as well.
Consequences:
Gain Access
Remedy:
For Gentoo Linux:
Upgrade to the latest version of Xorg-x11 (6.8.2-r3 or later), as listed in GLSA 200509-07. See References.
For Red Hat Linux 2.1 (AS, ES, WS and Advanced Workstation):
Upgrade to the latest version of XFree86 (4.1.0-73.EL or later). Refer to RHSA-2005:329-12 for more information. See References.
For Red Hat Linux (Xfree86):
Refer to RHSA-2005:501-20 or RHSA-2005:329-12 for patch, upgrade, or suggested workaround information. See References.
For Red Hat Linux 4.0 (AS, ES, WS and Desktop):
Upgrade to the latest version of Xorg-x11 (6.8.2-1.EL.13.16 or later). Refer to RHSA-2005:396-9 for more information. See References.
For Debian GNU/Linux:
Upgrade to the latest version of XFfree86 as listed below. Refer to Debian/GNU Security Advisory DSA-816-1 for more information. See References.
Debian/GNU 3.0 (woody7): 4.1.0-16woody7 or later
Debian/GNU 3.1 (sarge): 4.3.0.dfsg.1-14sarge1 or later
For Ubuntu Linux:
Refer to USN-182-1 for patch, upgrade, or suggested workaround information. See References.
For SUSE Linux:
