CVE Names:         CVE-2022-2509
====================================================================
1. Summary:

An update for gnutls and nettle is now available for Red Hat Enterprise
Linux 9.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AppStream (v. 9) - aarch64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux BaseOS (v. 9) - aarch64, ppc64le, s390x, x86_64

3. Description:

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)
