Package : linux-2.6 Vulnerability : several Problem-Type : local/remote Debian-specific: no CVE ID : CVE-2007-3104 CVE-2007-4997 CVE-2007-5500 CVE-2007-5904
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.
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.
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.
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.
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 compatability with or to take advantage of this update:
We recommend that you upgrade your 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.
