Updated kernel packages that fix several security issues and bugs in the
CentOS Linux 3 kernel are now available.
This security advisory has been rated as having moderate security impact
by the CentOS 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 ISDN CAPI subsystem that allowed a remote user to cause a
denial of service or potential privilege escalation. (CVE-2007-1217, Moderate)
* a flaw in the Bluetooth subsystem that allowed a local user to trigger an
information leak. (CVE-2007-1353, Low)
In addition to the security issues described above, fixes for the following
have been included:
* a race condition in the e1000 network driver that could cause ESB2
systems to be started without the RX unit being turned on.
* a related e1000 bug on ESB2 systems that could cause rlogin to fail.
CentOS would like to thank Ilja van Sprundel for reporting an issue fixed
in this erratum.
Note: The kernel-unsupported package contains various drivers and modules
that are unsupported and therefore might contain security problems that
have not been addressed.
All CentOS Linux 3 users are advised to upgrade their kernels
to the packages associated with their machine architecture and
configurations as listed in this erratum.
