Debian DSA-1428-2 : linux-2.6 - several vulnerabilities
high Nessus Plugin ID 29263
Synopsis
The remote Debian host is missing a security-related update.Description
Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :This is an update to DSA 1428-1 which omitted a reference to CVE-2007-5904.
- CVE-2007-3104 Eric Sandeen provided a backport of Tejun Heo's fix for a local denial of service vulnerability in sysfs. Under memory pressure, a dentry structure maybe reclaimed resulting in a bad pointer dereference causing an oops during a readdir.
- CVE-2007-4997 Chris Evans discovered an issue with certain drivers that make use of the Linux kernel's ieee80211 layer. A remote user could generate a malicious 802.11 frame that could result in a denial of service (crash). The ipw2100 driver is known to be affected by this issue, while the ipw2200 is believed not to be.
- CVE-2007-5500 Scott James Remnant diagnosed a coding error in the implementation of ptrace which could be used by a local user to cause the kernel to enter an infinite loop.
- CVE-2007-5904 Przemyslaw Wegrzyn discovered an issue in the CIFS filesystem that could allow a malicious server to cause a denial of service (crash) by overflowing a buffer.
These problems have been fixed in the stable distribution in version 2.6.18.dfsg.1-13etch5.
The following matrix lists additional packages that were rebuilt for compatibility with or to take advantage of this update :
Debian 4.0 (etch) fai-kernels 1.17+etch.13etch5 user-mode-linux 2.6.18-1um-2etch.13etch5
Solution
Upgrade the kernel package immediately and reboot the machine. If you have built a custom kernel from the kernel source package, you will need to rebuild to take advantage of these fixes.See Also
