=====================================================================

1. Summary:

An update for openssl 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:

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and
Transport Layer Security (TLS) protocols, as well as a full-strength
general-purpose cryptography library.

Security Fix(es):

* openssl: read buffer overflow in X.509 certificate verification
(CVE-2022-4203)

* openssl: timing attack in RSA Decryption implementation (CVE-2022-4304)

* openssl: double free after calling PEM_read_bio_ex (CVE-2022-4450)

* openssl: use-after-free following BIO_new_NDEF (CVE-2023-0215)

* openssl: invalid pointer dereference in d2i_PKCS7 functions
(CVE-2023-0216)

* openssl: NULL dereference validating DSA public key (CVE-2023-0217)

* openssl: X.400 address type confusion in X.509 GeneralName
(CVE-2023-0286)

* openssl: NULL dereference during PKCS7 data verification (CVE-2023-0401)

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):

* HMAC generation should reject key lengths < 112 bits or provide an
indicator in FIPS mode (BZ#2144000)

* In FIPS mode, openssl should set a minimum length for passwords in PBKDF2
(BZ#2144003)

* stunnel consumes high amount of memory when pestered with TCP connections
without a TLS handshake (BZ#2144008)

* In FIPS mode, openssl should reject SHAKE as digest for RSA-OAEP or
provide an indicator (BZ#2144010)

* In FIPS mode, openssl should reject RSASSA-PSS salt lengths larger than
the output size of the hash function used, or provide an indicator
(BZ#2144012)

* In FIPS mode, openssl should reject RSA signatures with X9.31 padding, or
provide an indicator (BZ#2144015)

* In FIPS mode, openssl should reject SHA-224, SHA-384, SHA-512-224, and
SHA-512-256 as hashes for hash-based DRBGs, or provide an indicator after
2023-05-16 (BZ#2144017)

* In FIPS mode, openssl should reject KDF input and output key lengths <
112 bits or provide an indicator (BZ#2144019)

* In FIPS mode, openssl should reject RSA keys < 2048 bits when using
EVP_PKEY_decapsulate, or provide an indicator (BZ#2145170)

* RHEL9.1 Nightly[0912] - error:03000093:digital envelope routines::command
not supported when git clone is run with configured ibmca engine backed by
libica.so.4 (OpenSSL 3.0) (BZ#2149010)

* OpenSSL FIPS checksum code needs update (BZ#2158412)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

For the update to take effect, all services linked to the OpenSSL library
must be restarted, or the system rebooted.
