CVE-2017-12868

The secureCompare method in lib/SimpleSAML/Utils/Crypto.php in SimpleSAMLphp 1.14.13 and earlier, when used with PHP before 5.6, allows attackers to conduct session fixation attacks or possibly bypass authentication by leveraging missing character conversions before an XOR operation.

CVE-2017-12873

SimpleSAMLphp 1.7.0 through 1.14.10 might allow attackers to obtain sensitive information, gain unauthorized access, or have unspecified other impacts by leveraging incorrect persistent NameID generation when an Identity Provider (IdP) is misconfigured.

CVE-2017-12869

The multiauth module in SimpleSAMLphp 1.14.13 and earlier allows remote attackers to bypass authentication context restrictions and use an authentication source defined in config/authsources.php via vectors related to improper validation of user input.

CVE-2017-12872

The (1) Htpasswd authentication source in the authcrypt module and (2) SimpleSAML_Session class in SimpleSAMLphp 1.14.11 and earlier allow remote attackers to conduct timing side-channel attacks by leveraging use of the standard comparison operator to compare secret material against user input.

CVE-2017-12870

SimpleSAMLphp 1.14.12 and earlier make it easier for man-in-the-middle attackers to obtain sensitive information by leveraging use of the aesEncrypt and aesDecrypt methods in the SimpleSAML/Utils/Crypto class to protect session identifiers in replies to non-HTTPS service providers.

CVE-2017-12871

The aesEncrypt method in lib/SimpleSAML/Utils/Crypto.php in SimpleSAMLphp 1.14.x through 1.14.11 makes it easier for context-dependent attackers to bypass the encryption protection mechanism by leveraging use of the first 16 bytes of the secret key as the initialization vector (IV).
