kernel security update

Type/Severity

Security Advisory: Important

Topic

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.

Description

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 the SCTP support that allowed a local user to cause a denial of
  service (crash) with a specific SO_LINGER value. (CVE-2006-4535, Important)
  
• a flaw in the hugepage table support that allowed a local user to cause a
  denial of service (crash). (CVE-2005-4811, Important)
  
• a flaw in the mprotect system call that allowed setting write permission
  for a read-only attachment of shared memory. (CVE-2006-2071, Moderate)
  
• a flaw in HID0[31] (en_attn) register handling on PowerPC 970 systems
  that allowed a local user to cause a denial of service. (crash)
  (CVE-2006-4093, Moderate)
  
• a flaw in the perfmon support of Itanium systems that allowed a local
  user to cause a denial of service by consuming all file descriptors.
  (CVE-2006-3741, Moderate)
  
• a flaw in the ATM subsystem. On systems with installed ATM hardware and
  configured ATM support, a remote user could cause a denial of service
  (panic) by accessing socket buffers memory after freeing them.
  (CVE-2006-4997, Moderate)
  
• a flaw in the DVB subsystem. On systems with installed DVB hardware and
  configured DVB support, a remote user could cause a denial of service
  (panic) by sending a ULE SNDU packet with length of 0. (CVE-2006-4623, Low)
  
• an information leak in the network subsystem that possibly allowed a
  local user to read sensitive data from kernel memory. (CVE-2006-0039, Low)
  

In addition, two bugfixes for the IPW-2200 wireless driver were included.
The first one ensures that wireless management applications correctly
identify IPW-2200 controlled devices, while the second fix ensures that
DHCP requests using the IPW-2200 operate correctly.

Red Hat would like to thank Olof Johansson, Stephane Eranian and Solar
Designer for reporting issues fixed in this erratum.

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.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
