CVE-2015-7503 [HIGH] CVE-2015-7503 php-ZendFramework2: Usage of vulnerable PKCS#1 v1.5 padding allows to recover RSA private key
CVE-2015-7503 php-ZendFramework2: Usage of vulnerable PKCS#1 v1.5 padding allows to recover RSA private key
It was found that `Zend\Crypt\PublicKey\Rsa\PublicKey` has a call to `openssl_public_encrypt()`, which uses PHP's default `$padding` argument, which specifies `OPENSSL_PKCS1_PADDING`, indicating usage of PKCS1v1.5 padding. This padding has a known vulnerability, the Bleichenbacher's chosen-ciphertext attack, that can be used to recover an RSA private key.
