Debian DSA-1294-1 : xfree86 - several vulnerabilities

high Nessus Plugin ID 25259

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been discovered in the X Window System, which may lead to privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2007-1003 Sean Larsson discovered an integer overflow in the XC-MISC extension, which might lead to denial of service or local privilege escalation.

- CVE-2007-1351 Greg MacManus discovered an integer overflow in the font handling, which might lead to denial of service or local privilege escalation.

- CVE-2007-1352 Greg MacManus discovered an integer overflow in the font handling, which might lead to denial of service or local privilege escalation.

- CVE-2007-1667 Sami Leides discovered an integer overflow in the libx11 library which might lead to the execution of arbitrary code. This update introduces tighter sanity checking of input passed to XCreateImage(). To cope with this an updated rdesktop package is delivered along with this security update. Another application reported to break is the proprietary Opera browser, which isn't part of Debian. The vendor has released updated packages, though.

Solution

Upgrade the XFree86 packages.

For the old stable distribution (sarge) these problems have been fixed in version 4.3.0.dfsg.1-14sarge4. This update lacks builds for the Sparc architecture, due to problems on the build host. Packages will be released once this problem has been resolved.

The stable distribution (etch) isn't affected by these problems, as the vulnerabilities have already been fixed during the Etch preparation freeze phase.
