Summary
Red Hat Security Advisory: : Updated 2.4 kernel fixes vulnerability
Severity
Important
Notes
Topic: Updated kernel packages for Red Hat Linux 7.1, 7.2, 7.3, and 8.0 are now available. These packages fix a ptrace-related vulnerability that can lead to elevated (root) privileges. [Updated 30 March 2003] Updated kernel packages for Red Hat Linux 7.2 ia64 have been added. [Updated 28 May 2003] Replacement kernel packages for Red Hat Linux 7.2 ia64 have been added; the previous packages did not contain the fix for the ptrace vulnerability.
Details: The Linux kernel handles the basic functions of the operating system. A vulnerability has been found in version 2.4.18 of the kernel. This vulnerability makes it possible for local users to gain elevated (root) privileges without authorization. This advisory includes updates for Red Hat Linux 7.1, 7.2, 7.3, and 8.0. All users of Red Hat Linux 7.1, 7.2, 7.3, and 8.0 should upgrade to these errata packages, which contain patches to fix the vulnerability.

CVE-2003-0127

The kernel module loader in Linux kernel 2.2.x before 2.2.25, and 2.4.x before 2.4.21, allows local users to gain root privileges by using ptrace to attach to a child process that is spawned by the kernel.
