It was found that Zend\Crypt\PublicKey\Rsa\PublicKey has a call to opensslpublicencrypt(), which uses PHP's default $padding argument, which specifies OPENSSLPKCS1PADDING, 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.

Doctrine Annotations before 1.2.7, Cache before 1.3.2 and 1.4.x before 1.4.2, Common before 2.4.3 and 2.5.x before 2.5.1, ORM before 2.4.8 or 2.5.x before 2.5.1, MongoDB ODM before 1.0.2, and MongoDB ODM Bundle before 3.0.1 use world-writable permissions for cache directories, which allows local users to execute arbitrary PHP code with additional privileges by leveraging an application with the umask set to 0 and that executes cache entries as code.
