Debian Security Advisory DSA 603-1                                        Martin Schulze
December 1st, 2004            

Package        : openssl
Vulnerability  : insecure temporary file
Problem-Type   : local/remote
Debian-specific: no
CVE ID         : CAN-2004-0975

Trustix developers discovered insecure temporary file creation in a
supplemental script (der_chop) of the openssl package which may allow
local users to overwrite files via a symlink attack.

For the stable distribution (woody) this problem has been fixed in
version 0.9.6c-2.woody.7.

For the unstable distribution (sid) this problem has been fixed in
version 0.9.7e-1.

We recommend that you upgrade your openssl package.

Upgrade Instructions

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
