Mandrake Linux Security Advisory : XFree86 (MDKSA-2004:012)

critical Nessus Plugin ID 14112

Synopsis

The remote Mandrake Linux host is missing one or more security updates.

Description

Two buffer overflow vulnerabilities were found by iDEFENSE in XFree86's parsing of the font.alias file. The X server, which runs as root, fails to check the length of user-provided input; as a result a malicious user could craft a malformed font.alias file causing a buffer overflow upon parsing, which could eventually lead to the execution of arbitrary code.

Additional vulnerabilities were found by David Dawes, also in the reading of font files.

The updated packages have a patch from David Dawes to correct these vulnerabilities.

Solution

Update the affected packages.
