===========================================================
Ubuntu Security Notice USN-94-1		     March 09, 2005
perl vulnerability
CAN-2005-0448
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

perl-modules

The problem can be corrected by upgrading the affected package to
version 5.8.4-2ubuntu0.4.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Paul Szabo discovered another vulnerability in the rmtree() function
in File::Path.pm. While a process running as root (or another user)
was busy deleting a directory tree, a different user could exploit a
race condition to create setuid binaries in this directory tree,
provided that he already had write permissions in any subdirectory of
that tree.
