RHSA-2006-0101: kernel

Vulnerability Assessment Summary
Check for the version of the kernel packages

Detailed Explanation for this Vulnerability Assessment

Updated kernel packages that fix several security issues in the Red Hat
Enterprise Linux 4 kernel are now available.

This security advisory has been rated as having important 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 below:

- a flaw in network IGMP processing that a permited a remote user on the
local network to cause a denial of service (disabling of multicast reports)
if the system is running multicast applications (CVE-2002-2185, moderate)

- a flaw which permited a local user to write to firmware on read-only
opened /dev/cdrom devices (CVE-2004-1190, moderate)

- a flaw in gzip/zlib handling internal to the kernel that may permit a
local user to cause a denial of service (crash) (CVE-2005-2458, low)

- a flaw in procfs handling during unloading of modules that permited a
local user to cause a denial of service or potentially gain rights
(CVE-2005-2709, moderate)

- a flaw in the SCSI procfs interface that permited a local user to cause a
denial of service (crash) (CVE-2005-2800, moderate)

- a flaw in 32-bit-compat handling of the TIOCGDEV ioctl that permited
a local user to cause a denial of service (crash) (CVE-2005-3044, important)

- a race condition when threads share memory mapping that permited local
users to cause a denial of service (deadlock) (CVE-2005-3106, important)

- a flaw when trying to mount a non-hfsplus filesystem using hfsplus that
permited local users to cause a denial of service (crash) (CVE-2005-3109,
moderate)

- a minor info leak with the get_thread_area() syscall that permited
a local user to view uninitialized kernel stack data (CVE-2005-3276, low)

- a flaw in mq_open system call that permited a local user to cause a denial
of service (crash) (CVE-2005-3356, important)

- a flaw in set_mempolicy that permited a local user on some 64-bit
architectures to cause a denial of service (crash) (CVE-2005-3358, important)

- a flaw in the auto-reap of child processes that permited a local user to
cause a denial of service (crash) (CVE-2005-3784, important)

- a flaw in the IPv6 flowlabel code that permited a local user to cause a
denial of service (crash) (CVE-2005-3806, important)

- a flaw in network ICMP processing that permited a local user to cause
a denial of service (memory exhaustion) (CVE-2005-3848, important)

- a flaw in file lease time-out handling that permited a local user to cause
a denial of service (log file overflow) (CVE-2005-3857, moderate)

- a flaw in network IPv6 xfrm handling that permited a local user to
cause a denial of service (memory exhaustion) (CVE-2005-3858, important)

- a flaw in procfs handling that permited a local user to read kernel memory
(CVE-2005-4605, important)

All Red Hat Enterprise Linux 4 users are advised to upgrade their kernels
to the packages associated with their machine architectures and
configurations as listed in this erratum.
