CyberRota Analysis

AI-Generated

The vulnerability affects the rust-openssl library versions 0.10.50 to 0.10.80, specifically within the CipherCtxRef::cipher_update_inplace function, which improperly sizes output buffers for AES key-wrap-with-padding ciphers. This flaw can lead to heap corruption due to the library writing beyond the allocated buffer, allowing attackers to manipulate memory and potentially execute arbitrary code. Organizations using affected versions of rust-openssl should prioritize upgrading to version 0.10.80 to mitigate this high-severity risk.

Original NVD Description

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.
