CVE-2021-3711
In order to decrypt SM2 encrypted data an application is expected to call the API function EVPPKEYdecrypt. Typically an application will call this function twice. The first time, on entry, the "out" parameter can be NULL and, on exit, the "outlen" parameter is populated with the buffer size...

Ubuntu 18.04 LTS / 20.04 LTS : OpenSSL vulnerabilities (USN-5051-1)
The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5051-1 advisory. John Ouyang discovered that OpenSSL incorrectly handled decrypting SM2 data. A remote attacker could use this issue to cause applications usi...
OpenSSL 1.1.1 < 1.1.1l Multiple Vulnerabilities
The version of OpenSSL installed on the remote host is prior to 1.1.1l. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.1.1l advisory. - ASN.1 strings are represented internally within OpenSSL as an ASN1STRING structure which contains a buffer holding the string data...
