CBL Mariner 2.0 Security Update: gnutls / libtasn1 (CVE-2024-12133)

medium Nessus Plugin ID 217104

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of gnutls / libtasn1 installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-12133 advisory.

- A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack. (CVE-2024-12133)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
