RHEL 2.1 / 3 : cyrus-sasl (RHSA-2004:546)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated cyrus-sasl packages that fix a setuid and setgid application
vulnerability are now available.

[Updated 7th October 2004] Revised cryus-sasl packages have been added
for Red Hat Enterprise Linux 3
the patch in the previous packages
broke interaction with ldap.

The cyrus-sasl package contains the Cyrus implementation of SASL. SASL
is the Simple Authentication and Security Layer, a method for adding
authentication support to connection-based protocols.

At application startup, libsasl and libsasl2 attempts to build a list
of all available SASL plug-ins which are available on the system. To
do so, the libraries search for and attempt to load every shared
library found within the plug-in directory. This location can be set
with the SASL_PATH environment variable.

In situations where an untrusted local user can affect the environment
of a privileged process, this behavior could be exploited to run
arbitrary code with the privileges of a setuid or setgid application.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2004-0884 to this issue.

Users of cyrus-sasl should upgrade to these updated packages, which
contain backported patches and are not vulnerable to this issue.
