Vulnerability Name:

CVE-2022-3996 (CCN-242005)

Assigned:2022-12-13
Published:2022-12-13
Updated:2023-03-31
Summary:OpenSSL is vulnerable to a denial of service, caused by a double locking flaw when an X.509 certificate contains a malformed policy constraint and policy processing is enabled. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition on the web server.
