7.5 · HIGH

Published Jun 5, 2014 gnu CWE-131 EPSS 3.79% (89th pctl) AV:N/AC:L/Au:N/C:P/I:P/A:P

Overview

CVE-2014-3468 is a high-severity vulnerability affecting gnu gnutls. It was published on June 5, 2014 and has a CVSS 2.0 base score of 7.5 (HIGH).

This vulnerability has a CVSS 2.0 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical Description

The asn1_get_bit_der function in GNU Libtasn1 before 3.6 does not properly report an error when a negative bit length is identified, which allows context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data.

Remediation

Check the references section for vendor advisories and patches from gnu. Update gnutls to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
