Red Hat Security Advisory

Synopsis: Updated cyrus-sasl packages fix security flaw
Advisory ID: RHSA-2004:546-01
Issue date: 2004-10-07
Updated on: 2004-10-07
Product: Red Hat Enterprise Linux
Keywords: environment
CVE Names: CAN-2004-0884
----------------------------------------------------------------------

1. Summary:

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, ppc64, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

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 CAN-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.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:

up2date
