RHEL 2.1 : kernel (RHSA-2004:069)

high Nessus Plugin ID 12469

Synopsis

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

Description

Updated kernel packages that fix a security vulnerability which may allow local users to gain root privileges are now available.

[Updated 5 March 2004] Added kernel-headers packages

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

Paul Starzetz discovered a flaw in return value checking in mremap() in the Linux kernel versions 2.4.24 and previous that may allow a local attacker to gain root privileges. No exploit is currently available; however this issue is exploitable. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0077 to this issue.

Arjan van de Ven discovered a flaw in ncp_lookup() in ncpfs that could allow local privilege escalation. ncpfs is only used to allow a system to mount volumes of NetWare servers or print to NetWare printers. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0010 to this issue.

All users are advised to upgrade to these errata packages, which contain backported security patches that correct these issues.

Red Hat would like to thank Paul Starzetz from ISEC for reporting this issue CVE-2004-0077.

Solution

Update the affected packages.
