ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING structure which contains a buffer holding the string data and a field holding the buffer length. Rated high severity (CVSS 7.4), this vulnerability is remotely exploitable, no authentication required. This Out-of-bounds Read vulnerability could allow attackers to read data from memory outside the intended buffer boundaries.
In order to decrypt SM2 encrypted data an application is expected to call the API function EVP_PKEY_decrypt(). Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Buffer Copy without Size Check vulnerability could allow attackers to overflow a buffer to corrupt adjacent memory.
The X.509 GeneralName type is a generic type for representing different types of names. Rated medium severity (CVSS 5.9), this vulnerability is remotely exploitable, no authentication required. This NULL Pointer Dereference vulnerability could allow attackers to crash the application by dereferencing a null pointer.
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling. Rated medium severity (CVSS 5.9), this vulnerability is remotely exploitable, no authentication required.
