A new libnasl/nessus vulnerability update is available for Ubuntu Linux. Here the announcement:

Ubuntu Security Notice USN-279-1 May 03, 2006
libnasl vulnerability
CVE-2006-2093
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)

The following packages are affected:

libnasl2

The problem can be corrected by upgrading the affected package to
version 2.2.3-1ubuntu0.1 (libnasl-dev and libnasl2) and
2.2.4-1ubuntu0.1 (libnasl-dev and libnasl2). After a standard system
upgrade you need to restart nessusd to effect the necessary changes.

Details follow:

Jayesh KS discovered that the nasl_split() function in the NASL
(Nessus Attack Scripting Language) library did not check for a
zero-length separator argument, which lead to an invalid memory
allocation. This library is primarily used in the Nessus security
scanner; a remote attacker could exploit this vulnerability to cause
the Nessus daemon to crash.

Updated packages for Ubuntu 5.04:
