Subject: [USN-70-1] Perl DBI module vulnerability

===========================================================
Ubuntu Security Notice USN-70-1		   January 25, 2005
libdbi-perl vulnerabilities
CAN-2005-0077
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

libdbi-perl

The problem can be corrected by upgrading the affected package to
version 1.42-3ubuntu0.1.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Javier Fern?ndez-Sanguino Pe?a from the Debian Security Audit Project
discovered that the module DBI::ProxyServer in Perl's DBI library
created a PID file in an insecure manner. This could allow a symbolic
link attack to create or overwrite arbitrary files with the privileges
of the user invoking a program using this module (like 'dbiproxy').

Now the module does not create a such a PID file by default.
