Low: openssl and openssl-fips-provider security update

Published Apr 30, 2024 · Updated Oct 29, 2026

Ecosystem: AlmaLinux

Summary

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)
