The _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguished Name (DN).

Security readout for executives and security teams

CVE-2008-4989 is a certificate validation flaw in GnuTLS before 2.6.1. A network attacker in a man-in-the-middle position could make a spoofed certificate appear trusted by abusing how certificate chains were accepted, undermining TLS identity checks. Exposure is likely where applications or operating system packages use libgnutls versions before 2.6.1 for X.509 certificate verification. The bundle does not enumerate every affected product; distribution advisories indicate multiple Linux vendors shipped fixes. Treat this as high priority on legacy systems because it weakens TLS trust and can enable credential or data interception. Modern, fully patched systems are unlikely to be exposed. Mitigation focus: Upgrade GnuTLS to 2.6.1 or a vendor-fixed package.; Apply relevant distribution advisories for Ubuntu, Red Hat, Gentoo, Mandriva, SUSE, and similar systems.; Restart or rebuild services using libgnutls after patching..
