Vulnerability Title
rust-openssl: Deriver::derive and PkeyCtxRef::derive can overflow short buffers on OpenSSL 1.1.1
Vulnerability Description
rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.27 to before 0.10.78, Deriver::derive (and PkeyCtxRef::derive) sets len = buf.len() and passes it as the in/out length to EVP_PKEY_derive, relying on OpenSSL to honor it. On OpenSSL 1.1.x, X25519, X448, DH and HKDF-extract ignore the incoming *keylen, unconditionally writing the full shared secret (32/56/prime-size bytes). A caller passing a short slice gets a heap/stack overflow from safe code. OpenSSL 3.x providers do check, so this only impacts older OpenSSL. This vulnerability is fixed in 0.10.78.

Vulnerability Title
rust-openssl 安全漏洞
Vulnerability Description
rust-openssl是rust-openssl开源的一个用于与 OpenSSL 库进行交互的库。 rust-openssl 0.9.27版本至0.10.78之前版本存在安全漏洞,该漏洞源于Deriver::derive设置len = buf.len()并将其作为输入/输出长度传递给EVP_PKEY_derive,在OpenSSL 1.1.x上X25519、X448、DH和HKDF-extract忽略传入的*keylen,无条件写入完整共享密钥,导致安全代码出现堆/栈溢出。
