NVD Description

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

rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.10.50 until 0.10.80, CipherCtxRef::cipher_update_inplace in openssl/src/cipher_ctx.rs 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 issue is fixed in version 0.10.80.
