Debian DSA-563-3 : cyrus-sasl - unsanitised input

high Nessus Plugin ID 15661

Synopsis

The remote Debian host is missing a security-related update.

Description

This advisory is an addition to DSA 563-1 and 563-2 which weren't able to supersede the library on sparc and arm due to a different version number for them in the stable archive. Other architectures were updated properly. Another problem was reported in connection with sendmail, though, which should be fixed with this update as well.

Solution

Upgrade the libsasl packages.

For the stable distribution (woody) this problem has been fixed in version 1.5.27-3.1woody5.

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.
