CVE-2012-1569: n/a vulnerability

CVE-2012-1569: The asn1_get_length_der function in decoding.c in GNU Libtasn1 before 2.12, as used in GnuTLS before 3.0.16...

The asn1_get_length_der function in decoding.c in GNU Libtasn1 before 2.12, as used in GnuTLS before 3.0.16 and other products, does not properly handle certain large length values, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) or possibly have unspecified other impact via a crafted ASN.1 structure.

Security readout for executives and security teams

This flaw affects older GNU Libtasn1 and software using it, including older GnuTLS. A malformed ASN.1 structure can crash affected applications, creating denial-of-service risk for services that parse untrusted certificates or ASN.1 data. Exposure is most likely on legacy Linux systems or applications using vulnerable Libtasn1 or GnuTLS builds to process remote ASN.1, DER, certificate, or TLS-related input. Treat this as a legacy dependency remediation item, especially for externally reachable services. Business risk is primarily service outage, with incomplete evidence for broader impact. Mitigation focus: Upgrade GNU Libtasn1 to 2.12 or later where vendor guidance supports it.; Upgrade GnuTLS to 3.0.16 or later where applicable.; Apply relevant vendor security updates from Red Hat, Ubuntu, Fedora, SUSE, or Oracle..
