Redhat : Security Vulnerabilities, CVEs, Published In May 2005 (Denial of service)

The secure script in LogWatch before 2.6-2 allows attackers to prevent LogWatch from detecting malicious activity via certain strings in the secure file that are later used as part of a regular expression, which causes the parser to crash, aka "logwatch log processing regular expression DoS."

The xattr file system code, as backported in Red Hat Enterprise Linux 3 on 64-bit systems, does not properly handle certain offsets, which allows local users to cause a denial of service (system crash) via certain actions on an ext3 file system with extended attributes enabled.

Unknown vulnerability in Linux kernel 2.4.x, 2.5.x, and 2.6.x allows NFS clients to cause a denial of service via O_DIRECT.

A regression error in the Red Hat Enterprise Linux 4 kernel 4GB/4GB split patch omits an "access check," which allows local users to cause a denial of service (crash).

Heap-based buffer overflow in less in Red Hat Enterprise Linux 3 allows attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted file, as demonstrated using the UTF-8 locale.
