Ubuntu 8.10 : linux vulnerability (USN-662-1)

Reporter Ubuntu Security Notice (C) 2008-2019 Canonical, Inc. / NASL script (C) 2009-2019 and is owned by Tenable, Inc. or an Affiliate thereof.

Description

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.
