RHEL 6 : gnutls (Unpatched Vulnerability)

medium Nessus Plugin ID 198376

Synopsis

The remote Red Hat 6 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

 - libtasn1: asn1_get_bit_der() can return negative bit length (CVE-2014-3468)

 - gnutls: HMAC-SHA-384 vulnerable to Lucky thirteen attack due to use of wrong constant (CVE-2018-10845)

 - 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. (CVE-2012-1569)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
