Debian Security Advisory DSA 563-2 security@debian.org
http://www.debian.org/security/ Martin Schulze
October 12th, 2004 http://www.debian.org/security/faq
---------------------------------------------------------------------------

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.
