https://bugzilla.ubuntu.com/show_bug.cgi?id=8459
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

sharutils

The problem can be corrected by upgrading the affected package to
version 1:4.2.1-10ubuntu0.2.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Joey Hess discovered that "unshar" created temporary files in an
insecure manner. This could allow a symbolic link attack to create or
overwrite arbitrary files with the privileges of the user invoking the
program.
