CVE-2026-41676

CVE-2026-41676 affects rust-openssl bindings. From 0.9.27 to before 0.10.78, Deriver::derive and PkeyCtxRef::derive incorrectly pass in/out lengths to EVP_PKEY_derive by using len = buf.len(). On OpenSSL 1.1.x, X25519, X448, DH and HKDF-extract ignore this incoming keylen and write the full share...

CVE-2026-41681

CVE-2026-41681 affects rust-openssl OpenSSL bindings. From 0.10.39 through before 0.10.78, EVP_DigestFinal() writes EVP_MD_CTX_size(ctx) to the output buffer. If the destination is smaller, MdCtxRef::digest_final() writes past the end, usually corrupting the stack, and this is reachable from safe...

CVE-2026-41677

CVE-2026-41677 affects the rust-openssl bindings for Rust. From 0.9.0 up to before 0.10.78, the *_from_pem_callback APIs did not validate the length returned by the user’s callback, allowing a password callback that returns more data than the destination buffer to cause an over-read in some OpenS...

CVE-2018-20997

CVE-2018-20997 affects the openssl crate for Rust prior to 0.10.9, describing a use-after-free in CMS Signing. The provided documents do not include patch versions, mitigations, or explicit exploitation details; severity is cited as high/critical in external references (e.g., CVSS), but no exploi...

CVE-2026-41678

CVE-2026-41678 affects rust-openssl bindings. The aes::unwrap_key() function contains an inverted assertion (out.len() + 8 = in_.len() - 8, allowing potential out-of-bounds writes when buffers are smaller than required. This vulnerability is limited to versions before 0.10.78; 0.10.78 fixes the i...
