NewStart CGSL CORE 5.04 / MAIN 5.04 : gcc Vulnerability (NS-SA-2019-0023)

medium Nessus Plugin ID 127181

Language:

Synopsis

The remote machine is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has gcc packages installed that are affected by a vulnerability:

 - Under certain circumstances, the ix86_expand_builtin function in i386.c in GNU Compiler Collection (GCC) version 4.6, 4.7, 4.8, 4.9, 5 before 5.5, and 6 before 6.4 will generate instruction sequences that clobber the status flag of the RDRAND and RDSEED intrinsics before it can be read, potentially causing failures of these instructions to go unreported. This could potentially lead to less randomness in random number generation.
 (CVE-2017-11671)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL gcc packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
