openssl: heap buffer overflow in CMS key unwrapping

A flaw was found in OpenSSL. A crafted CMS Cryptographic Message Syntax message can cause an 8-byte out-of-bounds heap write when it is decrypted with CMSdecrypt. This issue occurs because the CMS decryption process incorrectly sizes the key-unwrap output buffer when using the AES-WRAP-PAD unwrap...

php: ext/openssl: memory corruption in openssl_encrypt with AES-WRAP-PAD

A flaw was found in the OpenSSL extension of PHP. The AES-WRAP-PAD algorithm implementation uses the size of the plaintext length without accounting for the RFC 5649 expansion to allocate the output buffer for the AES key-wrap-with-padding operation. This may lead to an undersized memory allocati...
