Red Hat 2002-263 Security Check

high Log Correlation Engine Plugin ID 801576

Synopsis

The remote host is missing a security update.

Description

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 allow 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.

Solution

Update the affected package(s).
