Moderate: kernel security update
Security Advisory: Moderate
Updated kernel packages that fix a number of security issues as well as
other bugs are now available for Red Hat Enterprise Linux 2.1 (32 bit
This security advisory has been rated as having moderate security impact by
the Red Hat Security Response Team.
The Linux kernel handles the basic functions of the operating system.
These new kernel packages contain fixes for the security issues described
- a flaw in the ATM subsystem affecting systems with installed ATM hardware
and configured ATM support that allowed a remote user to cause a denial of
service (panic) by accessing socket buffer memory after it has been freed
- a flaw in the DVD handling of the CDROM driver that could be used
together with a custom built USB device to gain root privileges
In addition to the security issues described above, the following bugs are
- a potential overflow condition when reading /proc/devices
- uninitialized memory in cdrom_init() that can lead to a crash at install time
- a potential page corruption bug in /proc/kcore
- a race condition when reading vmalloc()ed regions via /proc/kcore
All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels
to these updated packages, which contain backported fixes to correct these
