CVE-2015-5276 Information

Description

The std::random_device class in libstdc++ in the GNU Compiler Collection (aka GCC) before 4.9.4 does not properly handle short reads from blocking sources which makes it easier for context-dependent attackers to predict the random values via unspecified vectors.
