The remote Red Hat host is missing one or more security updates.
Updated kernel packages that fix security issues and bugs in the Red
Hat Enterprise Linux 5 kernel are now available.
This update 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 following security
* a flaw in the key serial number collision avoidance algorithm of the
keyctl subsystem that allowed a local user to cause a denial of
service (CVE-2007-0006, Important)
* a flaw in the Omnikey CardMan 4040 driver that allowed a local user
to execute arbitrary code with kernel privileges. In order to exploit
this issue, the Omnikey CardMan 4040 PCMCIA card must be present and
the local user must have access rights to the character device created
by the driver. (CVE-2007-0005, Moderate)
* a flaw in the core-dump handling that allowed a local user to create
core dumps from unreadable binaries via PT_INTERP. (CVE-2007-0958,
In addition to the security issues described above, a fix for a kernel
panic in the powernow-k8 module, and a fix for a kernel panic when
booting the Xen domain-0 on system with large memory installations
have been included.
Red Hat would like to thank Daniel Roethlisberger for reporting an
issue fixed in this erratum.
Red Hat Enterprise Linux 5 users are advised to upgrade their kernels
to the packages associated with their machine architecture and
configurations as listed in this erratum.
