random_compat versions prior to 2.0 are affected by a security vulnerability related to the insecure usage of Cryptographically Secure Pseudo-Random Number Generators (CSPRNG). The affected versions use openssl_random_pseudo_bytes(), which may result in insufficient entropy and compromise the security of generated random numbers.

In order to verify Signatures on Logoutrequests and LogoutResponses we use the verifySignature of the class XMLSecurityKey from the xmlseclibs library. That method end up calling openssl_verify() depending on the signature algorithm used. The openssl_verify() function returns 1 when the signature was successfully verified, 0 if it failed to verify with the given key, and -1 in case an error occurs. PHP allows translating numerical values to boolean implicitly, with the following correspondences: - 0 equals false. - Non-zero equals true. This means that an implicit conversion to boolean of the values returned by openssl_verify() will convert an error state, signaled by the value -1, to a successful verification of the signature (represented by the boolean true). The LogoutRequest/LogoutResponse signature validator was performing an implicit conversion to boolean of the values returned by the verify() method, which subsequently will return the same output as openssl_verify() under mos...

The encryption and decryption process were vulnerable against the Bleichenbacher's attack, which is a padding oracle vulnerability disclosed in the 98'. The issue was about the wrong padding utilized, which allowed to retrieve the encrypted content. The OPENSSL_PKCS1_PADDING version, aka PKCS v1.5 was vulnerable (is the one set by default when using openssl_* methods), while the PKCS v2.0 isn't anymore (it's also called OAEP). A fix for this vulnerability was merged at https://github.com/Cosmicist/AsymmetriCrypt/pull/5/commits/a0318cfc5022f2a7715322dba3ff91d475ace7c6.
