However, proof of concept for this vulnerability is available.ĬVSSv3.1: 7.1 We are not aware of malware exploiting this vulnerability. Is there known malware, which exploits this vulnerability? This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Full software list in CPE2.3 format available after registration.Ĭan this vulnerability be exploited remotely?.However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will accept and hence trigger this attack. Note that an unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of EDIPARTYNAME. OpenSSL's s_server, s_client and verify tools have support for the "-crl_download" option which implements automatic CRL downloading and this attack has been demonstrated to work against those tools. This checking happens prior to the signatures on the certificate and CRL being verified. Note that some applications automatically download CRLs based on a URL embedded in a certificate. For example if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then this may occur.

If an attacker can control both items being compared then that attacker could trigger a crash. A remote attacker can trigger denial of service conditions via the API functions TS_RESP_verify_response and TS_RESP_verify_token). The vulnerability exists due to a NULL pointer dereference error. The vulnerability allows a remote attacker to perform a denial of service (DoS) attack. CVSSv3.1: 5.9 ĬWE-ID: CWE-476 - NULL Pointer Dereference
