Subject: [USN-24-1] openssl script vulnerability

===========================================================
Ubuntu Security Notice USN-24-1		  November 11, 2004
openssl script vulnerability
CAN-2004-0975
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

openssl

The problem can be corrected by upgrading the affected package to
version 0.9.7d-3ubuntu0.1.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Recently, Trustix Secure Linux discovered a vulnerability in the
openssl package. The auxiliary script "der_chop" created temporary
files in an insecure way, which could allow a symlink attack to create
or overwrite arbitrary files with the privileges of the user invoking
the program.
