rust-openssl vulnerable to heap buffer overflow when encrypting with AES key-wrap-with-padding

也稱為:GHSA-xv59-967r-8726CGA-6jq3-qvwq-qj6xDEBIAN-CVE-2026-44662

描述

`CipherCtxRef::cipher_update`, `CipherCtxRef::cipher_update_vec`, and `symm::Crypter::update` incorrectly sized output buffers when used with AES key-wrap-with-padding ciphers (`EVP_aes_{128,192,256}_wrap_pad`). For a non-multiple-of-8 input, OpenSSL writes up to 7 bytes past the end of the caller's buffer or Vec, producing attacker-controllable heap corruption when the plaintext length is attacker-influenced. This only impacts users using AES key-wrap-with-padding ciphers.
