Debian Security Advisory

DSA-568-1 cyrus-sasl-mit -- unsanitised input

Date Reported:

16 Oct 2004

Affected Packages:

cyrus-sasl-mit

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 275498.
In Mitre's CVE dictionary: CVE-2004-0884.

More information:

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.

Fixed in:

Debian GNU/Linux 3.0 (woody)
