Name of the Vulnerable Software and Affected Versions Apache HTTP Server versions 2.4.18 through 2.4.39

Description The issue is related to the implementation of the HTTP/2 network protocol in the Apache HTTP Server, which could allow an attacker to cause a denial of service. Using fuzzed network input, the http/2 session handling could be made to read memory after being freed, during connection shutdown.

Recommendations For Apache HTTP Server versions 2.4.18 through 2.4.39, consider disabling the http/2 protocol until a patch is available. As a temporary workaround, restrict access to the http/2 module to minimize the risk of exploitation. Avoid using fuzzed network input in the affected API endpoints until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
