CVE-2017-11671
4.0 · MEDIUMOverview
CVE-2017-11671 is a medium-severity vulnerability affecting gnu gcc. It was published on July 26, 2017 and has a CVSS 3.0 base score of 4.0 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 4.0, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from gnu. Update gcc to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
