Package        : cyrus-sasl-mit
Vulnerability  : unsanitised input
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2004-0884
Debian Bug     : 275498

A vulnerability has been discovered in the Cyrus implementation of the
SASL library, the Simple Authentication and Security Layer, a method
for adding authentication support to connection-based protocols.  The
library honors the environment variable SASL_PATH blindly, which
allows a local user to link against a malicious library to run
arbitrary code with the privileges of a setuid or setgid application.

The MIT version of the Cyrus implementation of the SASL library 
provides bindings against MIT GSSAPI and MIT Kerberos4.

For the stable distribution (woody) this problem has been fixed in
version 1.5.24-15woody3.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your libsasl packages.


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
footer to the proper configuration.
