Fedora 2004-111 Security Check



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 respectively.

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 userspace.

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.
