CVE-2024-28835: Gnutls: potential crash during chain building/verification

Security readout for executives and security teams

CVE-2024-28835 can make GnuTLS tools crash when processing a specially crafted certificate bundle. The known impact is denial of service, not data theft or code execution. Business urgency is moderate, mainly for systems or workflows that verify user-supplied PEM certificate bundles. Exposure is most likely where vulnerable GnuTLS packages are installed and certtool verifies certificate bundles from untrusted or semi-trusted sources. Source data lists RHEL 9, RHEL 10, and RHEL 9.2 EUS as affected, RHEL 8 as unaffected, and RHEL 6/7 as unknown. Treat as routine-to-priority patching, not an emergency, unless certificate validation workflows process untrusted input at scale. Prioritize internet-facing services only if they invoke vulnerable local verification paths using externally supplied PEM bundles. Mitigation focus: Apply vendor-provided GnuTLS updates from Red Hat, Debian, or NetApp where applicable.; Avoid verifying untrusted PEM bundles with vulnerable certtool until updated.; Restrict who can submit certificate bundles to validation workflows..
