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 issues:
* a flaw in the mount handling routine for 64-bit systems that allowed a
local user to cause denial of service (CVE-2006-7203, Important).
* a flaw in the PPP over Ethernet implementation that allowed a remote user
to cause a denial of service (CVE-2007-2525, Important).
* a flaw in the Bluetooth subsystem that allowed a local user to trigger an
information leak (CVE-2007-1353, Low).
* a bug in the random number generator that prevented the manual seeding of
the entropy pool (CVE-2007-2453, Low).
In addition to the security issues described above, fixes for the following
have been included:
* a race condition between ext3_link/unlink that could create an orphan
inode list corruption.
* a bug in the e1000 driver that could lead to a watchdog timeout panic.
Red Hat Enterprise Linux 5 users are advised to upgrade to these packages,
which contain backported patches to correct these issues.
