Name of the Vulnerable Software and Affected Versions: Apache versions 2.0.40 through 2.0.45

Description: The issue is related to the authentication module in Apache, which does not handle threads safely when using the crypt r or crypt functions. This can lead to a denial of service when a threaded MPM is used, causing failed Basic authentication with valid usernames and passwords.

Recommendations: For Apache versions 2.0.40 through 2.0.45, consider disabling the use of threaded MPM as a temporary workaround to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
