Subject: [USN-662-1] Linux kernel vulnerabilities

===========================================================
Ubuntu Security Notice USN-662-1          November 05, 2008
linux vulnerability
CVE-2008-3528, CVE-2008-4395
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 8.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

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

Ubuntu 8.10:
  linux-image-2.6.27-7-generic    2.6.27-7.16
  linux-image-2.6.27-7-server     2.6.27-7.16
  linux-image-2.6.27-7-virtual    2.6.27-7.16

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

Details follow:

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)
