Loginrust-openssl: Potential out-of-bounds write in `CipherCtxRef::cipher_update_inplace` for AES-KW-PAD ciphers
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.| Typ | Quelle | Score | Percentile |

CWE-131 Incorrect Calculation of Buffer Size
The product does not correctly calculate the size to be used when allocating a buffer, which could lead to a buffer overflow.
CWE-787 Out-of-bounds Write
The product writes data past the end, or before the beginning, of the intended buffer.
