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

high Nessus Plugin ID 15666

Synopsis

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

Description

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.

Solution

Upgrade the libsasl packages.

For the stable distribution (woody) this problem has been fixed in version 1.5.24-15woody3.
