CVE-2011-2503

Name of the Vulnerable Software and Affected Versions SystemTap versions prior to 1.6

Description The issue allows local users to gain privileges via a race condition between the signature validation and the module initialization in the insert module function. This can lead to a disruption of confidentiality, integrity, and availability of protected information. The exploitation of the vulnerabilities can be carried out locally.

Recommendations For SystemTap versions prior to 1.6, update to version 1.6 or later to resolve the issue. As a temporary workaround, consider disabling the insert module function until a patch is available. Restrict access to the vulnerable module to minimize the risk of exploitation. Avoid using the vulnerable function until the issue is resolved.
