NVD Description

Note: Versions mentioned in the description apply only to the upstream sccache package and not the sccache package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.10.0 to before 0.10.79, 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. This vulnerability is fixed in 0.10.79.
