Package        : cyrus-sasl
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.

For the stable distribution (woody) this problem has been fixed in
version 1.5.27-3woody2.

For the unstable distribution (sid) this problem has been fixed in
version 1.5.28-6.2 of cyrus-sasl and in version 2.1.19-1.3 of
cyrus-sasl2.

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.
