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

high Nessus Plugin ID 15441

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.

Solution

Update the affected packages.
