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

This advisory corrects DSA 563-1 which contained a library that caused
other programs to fail unindented.

For the stable distribution (woody) this problem has been fixed in
version 1.5.27-3woody3.

For reference the advisory text follows:

  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 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
