high Nessus Plugin ID 166009

Language:

Synopsis

The remote Red Hat host is missing a security update.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2022:6854 advisory.

The gnutls packages provide the GNU Transport Layer Security (GnuTLS) library, which implements cryptographic algorithms and protocols such as SSL, TLS, and DTLS.

Nettle is a cryptographic library that is designed to fit easily in almost any context: In crypto toolkits for object-oriented languages, such as C++, Python, or Pike, in applications like LSH or GNUPG, or even in kernel space.

The following packages have been upgraded to a later upstream version: gnutls (3.7.6), nettle (3.8).

Security Fix(es):

* gnutls: Double free during gnutls_pkcs7_verify. (CVE-2022-2509)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* [IBM 9.1] [P10] POWER10 performance enhancements for cryptography: nettle - incremental work (BZ#2102589)

* Allow enabling KTLS in RHEL 9.1 (BZ#2108532)

* DES-CBC bag is decryptable under FIPS (BZ#2115314)

* allow signature verification using RSA keys <2k in FIPS mode (BZ#2119770)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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.
