high Nessus Plugin ID 12493

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated kernel packages that fix two privilege escalation vulnerabilities are now available.

The Linux kernel handles the basic functions of the operating system.

iSEC Security Research discovered a flaw in the ip_setsockopt() function code of the Linux kernel versions 2.4.22 to 2.4.25 inclusive.
This flaw also affects the 2.4.21 kernel in Red Hat Enterprise Linux 3 which contained a backported version of the affected code. A local user could use this flaw to gain root privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0424 to this issue.

iDefense reported a buffer overflow flaw in the ISO9660 filesystem code. An attacker could create a malicious filesystem in such a way that root privileges may be obtained if the filesystem is mounted. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0109 to this issue.

All Red Hat Enterprise Linux 3 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.
