CVE-2014-2208

The vulnerability CVE-2014-2208 affects Facebook HHVM prior to version 2.4.2. A CRLF injection in the LightProcess protocol implementation (hphp/util/light-process.cpp) allows remote attackers to cause arbitrary command execution by injecting a newline character before the end of a string. Affect...

CVE-2014-6229

The HashContext class in hphp/runtime/ext/exthash.cpp in Facebook HipHop Virtual Machine HHVM before 3.3.0 incorrectly expects that a certain key string uses '\0' for termination, which allows remote attackers to obtain sensitive information by leveraging read access beyond the end of the string,...

CVE-2014-5386

The mcryptcreateiv function in hphp/runtime/ext/mcrypt/extmcrypt.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...

CVE-2014-2209

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...

CVE-2014-6229

CVE-2014-6229 affects Facebook HHVM prior to 3.3.0. The HashContext class in hphp/runtime/ext/ext_hash.cpp improperly assumes a key string terminator as '\0', enabling read access beyond end of string and potentially truncation of an internal '\0' character. Impact is information disclosure and w...

CVE-2014-2208

CRLF injection vulnerability in the LightProcess protocol implementation in hphp/util/light-process.cpp in Facebook HipHop Virtual Machine HHVM before 2.4.2 allows remote attackers to execute arbitrary commands by entering a \n newline character before the end of a string...

CVE-2014-5386

CVE-2014-5386 affects Facebook HHVM: the mcrypt_create_iv function in hphp/runtime/ext/mcrypt/ext_mcrypt.cpp does not seed the random number generator before HHVM 3.3.0, which enables remote attackers to defeat cryptographic protections by reusing a single initialization vector. Root cause is lac...
