This vulnerability requires a corrupted input file to have already been introduced into your application\u2019s source code. This flaw could then induce a segmentation fault during compile time. However, it would be immediately apparent to the developer or operations team that something is wrong.\nIn a release pipeline which utilizes libiberty, a build failure would not prevent usage of existing stable builds, so while a flaw of this type could halt the roll out of new versions of your app, it cannot impact any apps which have already been built and deployed.\nIf this vulnerability were exploited, organizations which follow basic industry guidance for development and security (isolation of build environment, use of version control, and restriction of commit access) would be able to recover easily. Better prepared organizations would not even experience an outage as any problematic commits would be automatically reverted. For these reasons Red Hat Product Security has rated the impact as Low.", "threat_severity": "Low"}
