RHSA-2024:2447 - Security Advisory

Topic

An update for openssl and openssl-fips-provider is now available for Red Hat Enterprise Linux 9.

Red Hat Product Security has rated this update as having a security impact of Low. 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.

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: AES-SIV cipher implementation contains a bug that causes it to ignore empty associated data entries (CVE-2023-2975)
• openssl: Excessive time spent checking DH keys and parameters (CVE-2023-3446)
• OpenSSL: Excessive time spent checking DH q parameter value (CVE-2023-3817)
• openssl: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow (CVE-2023-5678)
• openssl: POLY1305 MAC implementation corrupts vector registers on PowerPC (CVE-2023-6129)
• openssl: Excessive time spent checking invalid RSA public keys (CVE-2023-6237)
• openssl: denial of service via null dereference (CVE-2024-0727)
