pyOpenSSL: DTLS cookie callback buffer overflow

A flaw was found in pyOpenSSL. The setcookiegeneratecallback callback function can be used to generate DTLS cookies. When the callback returns a cookie string or byte sequence longer than 256 bytes, a buffer overflow can be triggered due to a missing bounds checking before copying the data to a...

UBUNTU-CVE-2026-41676

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 EVPPKEYderive, relying on OpenSSL to honor it. On OpenSSL 1.1.x, X25519, X448, DH and HKDF-extra...
