CVE-2021-3711: Buffer Overflow
First published: Thu Aug 19 2021(Updated: )
OpenSSL is vulnerable to a buffer overflow, caused by improper bounds checking by the EVP_PKEY_decrypt() function within implementation of the SM2 decryption. By sending specially crafted SM2 content, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
