Upgrade openssl-sys to version 0.9.115 or higher.
Overview
openssl-sys is a package for OpenSSL bindings for the Rust programming language
Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the CipherCtxRef::cipher_update, CipherCtxRef::cipher_update_vec, and symm::Crypter::update functions when encrypting with AES key-wrap-with-padding ciphers. An attacker can cause heap corruption and potentially execute arbitrary code or crash the application by providing specially crafted input that results in output buffers being incorrectly sized.
