Rebased to kernel 2.6.20.3-rc1 :

http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.20 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.20.1 (The CVE fix in 2.6.20.1 is already in kernel-2.6.19-1.2911.6.5.fc6.) http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.20.2 Changelog for 2.6.20.3 is not available yet.

This release does not include Xen kernels.

CVE-2007-0005: A vulnerability has been reported in the Linux Kernel, which potentially can be exploited by malicious, local users to cause a DoS (Denial of Service) or gain escalated privileges.

The vulnerability is caused due to boundary errors within the ‘read()’ and ‘write()’ functions of the Omnikey CardMan 4040 driver. This can be exploited to cause a buffer overflow and may allow the execution of arbitrary code with kernel privileges.

CVE-2007-1000: A vulnerability has been reported in the Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service) or disclose potentially sensitive information.

The vulnerability is due to a NULL pointer dereference within the ‘ipv6_getsockopt_sticky()’ function in net/ipv6/ipv6_sockglue.c. This can be exploited to crash the kernel or disclose kernel memory.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
