RHSA-2002-263: kernel

Vulnerability Assessment Summary
Check for the version of the kernel packages

Detailed Explanation for this Vulnerability Assessment


The kernel in Red Hat Linux Advanced Server 2.1 is vulnerable to a local
denial of service attack. Updated packages are available which address this
vulnerability.

[Updated 28 August 2003]
Added CVE-2003-0461 to the list of security issues that were fixed by this
advisory (there are no changes to the packages themselves).

The Linux kernel handles the basic functions of the operating system.
A vulnerability in the Linux kernel has been discovered in which a non-root
user can cause the machine to freeze. This kernel addresses the
vulnerability.

Note: This bug is specific to the x86 architecture kernels only, and does
not affect ia64 or other architectures.

In addition, /proc/tty/driver/serial reveals the exact number of
characters used in serial links, which could permit local users to obtain
potentially sensitive information such as password lengths.

All users should upgrade to these errata packages, which are not vulnerable
to these issues.

Thanks go to Christopher Devine for reporting the vulnerability on Bugtraq,
and Petr Vandrovec for being the first to supply a fix to the community.
