Description

At application startup, libsasl and libsasl2 attempt to build a list of all 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.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
