Red Hat Security Advisory: kernel security update

Important

Multiple TCP/IP and ICMP implementations allow remote attackers to cause a denial of service (network throughput reduction for TCP connections) via a blind throughput-reduction attack using spoofed Source Quench packets, aka the "ICMP Source Quench attack." NOTE: CVE-2004-0790, CVE-2004-0791, and CVE-2004-1060 have been SPLIT based on different attacks; CVE-2005-0065, CVE-2005-0066, CVE-2005-0067, and CVE-2005-0068 are related identifiers that are SPLIT based on the underlying vulnerability. While CVE normally SPLITs based on vulnerability, the attack-based identifiers exist due to the variety and number of affected implementations and solutions that address the attacks instead of the underlying vulnerabilities.

The binfmt functionality in the Linux kernel, when "memory overcommit" is enabled, allows local users to cause a denial of service (kernel oops) via a malformed a.out binary.

Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux kernel 2.4 through 2.429-rc2 and 2.6 through 2.6.10 allows local users to execute arbitrary code by manipulating the VMA descriptor.

Unknown vulnerability in the system call filtering code in the audit subsystem for Red Hat Enterprise Linux 3 allows local users to cause a denial of service (system crash) via unknown vectors.
