NVD Description

Note: Versions mentioned in the description apply only to the upstream himmelblau-sso package and not the himmelblau-sso package as distributed by SLES. See How to fix? for SLES:16.0.0 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.
