CVE-2015-5276 (GCVE-0-2015-5276)

Vulnerability from cvelistv5

Published

Modified

Severity ?

CWE

Summary

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.
