F5 Networks BIG-IP : GnuTLS vulnerability (K53330207)

medium Nessus Plugin ID 123837

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

GnuTLS before 2.9.10 does not verify the activation and expiration dates of CA certificates, which allows man-in-the-middle attackers to spoof servers via a certificate issued by a CA certificate that is (1) not yet valid or (2) no longer valid. (CVE-2014-8155)

Impact

GnuTLS does not check activation and expiration dates of CA certificates. This can cause an application using GnuTLS to incorrectly accept a certificate as valid when its issuing CA is already expired.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K53330207.
