"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).

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."
