Debian 3.0: DSA 568-1 Critical: SASL Arbitrary Code Execution

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.
