NewStart CGSL MAIN 6.06 (SP) : gcc Vulnerability (NS-SA-2026-0008)

The remote NewStart CGSL host, running version MAIN 6.06 SP, has gcc packages installed that are affected by a vulnerability: - The POWER9 backend in GNU Compiler Collection GCC before version 10 could optimize multiple calls of the builtindarn intrinsic into a single call, thus reducing the...

Linux Distros Unpatched Vulnerability : CVE-2019-15847

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The POWER9 backend in GNU Compiler Collection GCC before version 10 could optimize multiple calls of the builtindarn intrinsic into a single call, thus reducing...

SUSE CVE-2019-15847

The POWER9 backend in GNU Compiler Collection GCC before version 10 could optimize multiple calls of the builtindarn intrinsic into a single call, thus reducing the entropy of the random number generator. This occurred because a volatile operation was not specified. For example, within a single...

The POWER9 backend in GNU Compiler Collection (GCC) before version 10 could optimize multiple calls of the __builtin_darn intrinsic into a single call thus reducing the entropy of the random number generator. This occurred because a volatile operation was not specified. For example within a single execution of a program the output of every __builtin_darn() call may be the same.
