The following CVEs were assigned by RedHat for these issues: CVE-2019-14871, CVE-2019-14872, CVE-2019-14873, CVE-2019-14874, CVE-2019-14875, CVE-2019-14876, CVE-2019-14877, CVE-2019-14878 More details about the issues are available here: https://census-labs.com/news/2020/01/31/multiple-null-pointer-dereference-vulnerabilities-in-newlib/ It is advised to update newlib installations to version 3.3.0 and make sure to build with the newlib-reent-check-verify 'configure' option enabled, to correctly address these issues. Kind Regards, Dimitris
