XZ Utils CVE-2024-3094: Block and Remediate with Harness SSCA

In March 2024, a critical vulnerability known as CVE-2024-3094 was discovered in XZ Utils, affecting versions 5.6.0 and 5.6.1, which are widely used in Linux distributions. This flaw allowed attackers to insert a backdoor using a modified build script and exploit the IFUNC mechanism in glibc to manipulate OpenSSH authentication. Various Linux distributions like Fedora, Debian, and openSUSE have been affected, prompting urgent updates and downgrades to earlier, secure versions. Harness Software Supply Chain Assurance (SSCA) provides a solution for identifying and mitigating this vulnerability by utilizing Software Bill of Materials (SBOMs) to detect affected deployments, blocking vulnerable versions in build pipelines, and tracking remediation progress. This proactive approach helps organizations maintain the integrity of their software supply chains by preventing the deployment of compromised software and enhancing overall security.
