Security Advisory - RHSA-2002:262-07
- -----------------------------------------------------------------------
- -------
Summary:
New kernel fixes local denial of service issue
The kernel in Red Hat Linux 7.1, 7.1K, 7.2, 7.3, and 8.0 are vulnerable
to a local denial of service attack. Updated packages are available
which address this vulnerability, as well as bugs in several drivers.
Description:
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, a bug in the maestro3 soundcard driver has been fixed as
well as a bug in the xircom pcmcia driver network driver and the tg3
network driver for Broadcom gigabit ethernet chips.
All users of Red Hat Linux 7.1, 7.1K, 7.2, 7.3, and 8.0 should upgrade
to these errata packages, which are not vulnerable to this issue.
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.
