The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. Under certain circumstances, the command line OCSP verify function reports successful verification when the varification in fact failed. In this case the incorrect successful response will also be accompanied by error messages showing the failure and contradicting the apparently successful result. When using the RC4-MD5 ciphersuite, which is disabled by default, an attacker is able to modify data in transit due to an incorrect use of the AAD data as the MAC key in OpenSSL 3.0. An attacker is not able to decrypt any communication. The used OpenSSL version improperly reuses memory when decoding certificates or keys. This can lead to a process termination and Denial of Service for long lived processes.
