CVE-2015-3216 (GCVE-0-2015-3216)

Vulnerability from cvelistv5 – Published: 2015-07-07 10:00 – Updated: 2024-08-06 05:39

Summary

Race condition in a certain Red Hat patch to the PRNG lock implementation in the ssleay_rand_bytes function in OpenSSL, as distributed in openssl-1.0.1e-25.el7 in Red Hat Enterprise Linux (RHEL) 7 and other products, allows remote attackers to cause a denial of service (application crash) by establishing many TLS sessions to a multithreaded server, leading to use of a negative value for a certain length field.

Severity

No CVSS data available.
