===========================================================
Ubuntu Security Notice USN-254-1	  February 21, 2006
noweb vulnerability
CVE-2005-3342
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)

The following packages are affected:

nowebm

The problem can be corrected by upgrading the affected package to
version 2.10c-3ubuntu1.1 (for Ubuntu 4.10), 2.10c-3.1ubuntu5.04.1 (for
Ubuntu 5.04), or 2.10c-3.1ubuntu5.10.1 (for Ubuntu 5.10).  In general,
a standard system upgrade is sufficient to effect the necessary
changes.

Details follow:

Javier Fernández-Sanguino Peña discovered that noweb scripts created
temporary files in an insecure way. This could allow a symlink attack
to create or overwrite arbitrary files with the privileges of the user
running noweb.
