Debian DSA-1479-1 : linux-2.6 - several vulnerabilities

High Nessus Plugin ID 30126

Synopsis

The remote Debian host is missing a security-related update.

Description

Several local 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 :

- CVE-2007-2878 Bart Oldeman reported a denial of service (DoS) issue in the VFAT filesystem that allows local users to corrupt a kernel structure resulting in a system crash. This is only an issue for systems which make use of the VFAT compat ioctl interface, such as systems running an 'amd64' flavor kernel.

- CVE-2007-4571 Takashi Iwai supplied a fix for a memory leak in the snd_page_alloc module. Local users could exploit this issue to obtain sensitive information from the kernel.

- CVE-2007-6151 ADLAB discovered a possible memory overrun in the ISDN subsystem that may permit a local user to overwrite kernel memory by issuing ioctls with unterminated data.

- CVE-2008-0001 Bill Roman of Datalight noticed a coding error in the linux VFS subsystem that, under certain conditions, can allow local users to remove directories for which they should not have removal privileges.

These problems have been fixed in the stable distribution in version 2.6.18.dfsg.1-17etch1.

Solution

Upgrade the kernel packages 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.
