Fedora 2004-111 Security Check

High Log Correlation Engine Plugin ID 801550


The remote host is missing a security update.


A memory leak was fixed in an error path in the do_fork() routine.
This was unlikely to have caused problems in real world situations.

The information leak fixed in the previous errata was also found to
affect XFS and JFS. The Common Vulnerabilities and Exposures project
(cve.mitre.org) assigned the names CVE-2004-0133 and CVE-2004-0181

A vulnerability in the OSS code for SoundBlaster 16 devices was
discovered by Andreas Kies. It is possible for local users with access
to the sound system to crash the machine (CVE-2004-0178).

An automated checked from http://www.coverity.com highlighted a range
checking bug in the i810 DRM driver. This was fixed by Andrea
Arcangeli and Chris Wright.

Arjan van de Ven discovered the framebuffer code was doing direct
userspace accesses instead of using correct interfaces to write to

Brad Spengler found a signedness issue in the cpufreq proc handler
which could lead to users being able to read arbitary regions of
kernel memory. This was fixed by Dominik Brodowski.

Shaun Colley found a potential buffer overrun in the panic() function.
As this function does not ever return, it is unlikely that this is
exploitable, but has been fixed nonetheless. The Common
Vulnerabilities and Exposures project (cve.mitre.org) assigned the
name CVE-2004-0394 to this issue.

Paul Starzetz and Wojciech Purczynski found a lack of bounds checking
in the MCAST_MSFILTER socket option which allows user code to write
into kernel space, potentially giving the attacker full root
priveledges. There has already been proof of concept code published
exploiting this hole in a local denial-of-service manner.
http://www.isec.pl/vulnerabilities/isec-0015-msfilter.txt has more
information. The Common Vulnerabilities and Exposures project
(cve.mitre.org) assigned the name CVE-2004-0424 to this issue.

The previous security errata actually missed fixes for several
important problems. This has been corrected in this update.


Update the affected package(s).
