RHEL 2.1 : kernel (RHSA-2003:195)

critical Nessus Plugin ID 12401

Synopsis

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

Description

Updated kernel packages for Red Hat Enterprise Linux are now available which address several security vulnerabilities.

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

Several security issues have been found that affect the Linux kernel :

Al Viro found a security issue in the tty layer whereby any user could cause a kernel oops. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0247 to this issue.

Andrea Arcangeli found an issue in the low-level mxcsr code in which a malformed address would leave garbage in cpu state registers. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0248 to this issue.

The TCP/IP fragment reassembly handling allows remote attackers to cause a denial of service (CPU consumption) via packets that cause a large number of hash table collisions, a vulnerability similar to CVE-2003-0244. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2003-0364 to this issue.

These kernels also contain updated fixes for the ioperm security issue, as well as fixes for a number of bugs.

It is recommended that users upgrade to these erratum kernels, which contain patches to correct these vulnerabilities.

Solution

Update the affected packages.
