"text": "This is a flaw in the GENERAL_NAME_cmp function of openssl which can be triggered when both its arguments are of the same type i.e. EDIPARTYNAME. \n\n1. Red Hat does not ship any applications compiled with openssl, which used the above function in a vulnerable way.\n\n2. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes, when comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate and when verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token). If an attacker can control both items being compared then that attacker could trigger a crash. For example, if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then a crash may be triggered.\n\nThird party applications compiled with openssl using the function GENERAL_NAME_cmp in a vulnerable way are affected by this flaw.\n\nGENERAL_NAME_cmp was added in 0.9.8k, therefore older versions of openssl are not affected by this flaw.",
