Facebook: Security Vulnerabilities
The mcrypt_create_iv function in hphp/runtime/ext/mcrypt/ext_mcrypt.cpp in Facebook HipHop Virtual Machine (HHVM) before 3.3.0 does not seed the random number generator, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by leveraging the use of a single initialization vector.

Facebook HipHop Virtual Machine (HHVM) before 3.1.0 does not drop supplemental group memberships within hphp/util/capability.cpp and hphp/util/light-process.cpp, which allows remote attackers to bypass intended access restrictions by leveraging group permissions for a file or directory.

Cross-site scripting (XSS) vulnerability in the Facebook app 14.0 and the Facebook Messenger app 10.0 for iOS allows remote attackers to inject arbitrary web script or HTML via a crafted filename extension that is improperly handled during MIME sniffing of chat traffic. NOTE: the vendor disputes the significance of this report, because the user must accept an interstitial warning before the HTML file content is rendered, and because the HTML content's origin is a sandbox domain
