Name of the Vulnerable Software and Affected Versions Keylime versions prior to 6.3.0

Description The issue arises from the Revocation Notifier in Keylime using a fixed /tmp path for a UNIX domain socket. This can be exploited by unprivileged users to prohibit Keylime operations.

Recommendations For versions prior to 6.3.0, update to version 6.3.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the fixed /tmp path used by the Revocation Notifier to minimize the risk of exploitation.
