The _gnutls_x509_oid2mac_algorithm function in lib/gnutls_algorithms.c in GnuTLS before 1.4.2 allows remote attackers to cause a denial of service (crash) via a crafted X.509 certificate that uses a hash algorithm that is not supported by GnuTLS, which triggers a NULL pointer dereference.

Security readout for executives and security teams

This is a denial-of-service flaw in very old GnuTLS versions before 1.4.2. A remote party could present a crafted X.509 certificate using an unsupported hash algorithm and crash software relying on vulnerable GnuTLS certificate handling. The provided sources indicate service interruption risk, not data theft or code execution. Exposure is most likely in legacy systems or embedded products still linked against GnuTLS versions before 1.4.2 and processing untrusted X.509 certificates. The bundle does not identify specific vendor products or CPEs. Treat this as a legacy resilience issue. It is unlikely to warrant emergency action unless old GnuTLS is present on exposed systems, but vulnerable deployments should be upgraded or retired because remote crashes can affect availability. Mitigation focus: Identify any systems using GnuTLS before 1.4.2.; Upgrade vulnerable GnuTLS deployments to 1.4.2 or later where supported.; Check operating system or appliance vendor advisories for packaged fixes..
