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.
