openssl: OpenSSL: Denial of Service due to heap out-of-bounds read in CMS password-based decryption

A flaw was found in OpenSSL. When processing attacker-supplied Cryptographic Message Syntax CMS data using password-based decryption, an attacker can choose a stream-mode Key Encryption Key KEK cipher. This can trigger a heap out-of-bounds read, potentially causing an application crash and leadin...
