Overview

openssl is a bindings for the Rust programming language.

Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the CipherCtxRef::cipher_update_inplace() function when handling AES key-wrap-with-padding ciphers. An attacker can cause heap corruption by providing a plaintext length that is not a multiple of 8, resulting in up to 7 bytes being written past the end of the output buffer.

Note: This is a bypass of the fix for the vulnerability described in CVE-2026-44662.
