Summary
rust-openssl: Potential out-of-bounds write in `CipherCtxRef::cipher_update_inplace` for AES-KW-PAD ciphers
Details

CipherCtxRef::cipher_update_inplace incorrectly sized output buffers when used with AES key-wrap-with-padding ciphers (EVPaes{128,192,256}wrappad). 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 method was missed in the fix for GHSA-xv59-967r-8726
