Ubuntu 6.06 LTS / 7.04 / 7.10 / 8.04 LTS : linux, linux-source-2.6.15/20/22 vulnerabilities (USN-637-1)

High Nessus Plugin ID 34048

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that there were multiple NULL pointer function dereferences in the Linux kernel terminal handling code. A local attacker could exploit this to execute arbitrary code as root, or crash the system, leading to a denial of service. (CVE-2008-2812)

The do_change_type routine did not correctly validation administrative users. A local attacker could exploit this to block mount points or cause private mounts to be shared, leading to denial of service or a possible loss of privacy. (CVE-2008-2931)

Tobias Klein discovered that the OSS interface through ALSA did not correctly validate the device number. A local attacker could exploit this to access sensitive kernel memory, leading to a denial of service or a loss of privacy. (CVE-2008-3272)

Zoltan Sogor discovered that new directory entries could be added to already deleted directories. A local attacker could exploit this, filling up available memory and disk space, leading to a denial of service. (CVE-2008-3275)

In certain situations, the fix for CVE-2008-0598 from USN-623-1 was causing infinite loops in the writev syscall. This update corrects the mistake. We apologize for the inconvenience.

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

Solution

Update the affected packages.
