NewCVE-2026-41677 (opens in a new tab)How to fix?
Upgrade openssl to version 0.10.78 or higher.
Overview
openssl is a bindings for the Rust programming language.
Affected versions of this package are vulnerable to Improper Validation of Specified Quantity in Input via the invoke_passwd_cb password callback trampoline in the OpenSSL PEM key-loading path. An attacker can leak adjacent stack bytes into the derived decryption key by supplying a password callback return value larger than the scratch buffer and triggering EcKey::private_key_from_pem_callback on OpenSSL 1.1 or LibreSSL. This can expose memory contents during private key decryption and produce incorrect key material for users loading encrypted PEM keys.
