Potential Information Disclosure in Zend\Crypt\PublicKey\Rsa\PublicKey
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, which can be used to decrypt arbitrary ciphertexts. Users should upgrade to a fixed version unless there are not using the RSA public key functionality.

Remote code execution in zend-mail via Sendmail adapter
A malicious user may be able to inject arbitrary parameters to the system Sendmail program. The attack is performed by providing additional quote characters within an address; when unsanitized, they can be interpreted as additional command line arguments, leading to the vulnerability.

Potential Information Disclosure and Insufficient Entropy in Zend\Captcha\Word
Zend generates a "word" for a CAPTCHA challenge by selecting a sequence of random letters from a character set. The selection is performed using PHP's internal `array_rand()` function. This function does not generate sufficient entropy due to its usage of `rand()` instead of more cryptographically secure methods such as `openssl_pseudo_random_bytes()`. This can potentially lead to information disclosure should an attacker be able to brute force the random number generation.
