USN-662-1: Linux kernel vulnerabilities

5 November 2008

Linux kernel vulnerabilities




It was discovered that the Linux kernel could be made to hang temporarily
when mounting corrupted ext2/3 filesystems. If a user were tricked into
mounting a specially crafted filesystem, a remote attacker could cause
system hangs, leading to a denial of service. (CVE-2008-3528)

Anders Kaseorg discovered that ndiswrapper did not correctly handle long
ESSIDs. For a system using ndiswrapper, a physically near-by attacker
could generate specially crafted wireless network traffic and execute
arbitrary code with root privileges. (CVE-2008-4395)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.10

After a standard system upgrade you need to reboot your computer to
effect the necessary changes.
