CVE-2022-29242

The CVE concerns the GOST engine (OpenSSL) used for Russian GOST crypto. The issue affects TLS clients using the GOST engine when the cipher suite TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC is negotiated and the server uses 512‑bit GOST keys, leading to a buffer overflow. The patch is in GOST e...
