GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

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

Vulnerability from cvelistv5 – Published: 2015-11-17 15:00 – Updated: 2024-08-06 06:41
VLAI
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.
Severity
