Red Hat Security Advisory: openssl security update
Multiple security vulnerabilities have been identified in OpenSSL, a widely used cryptographic library implementing SSL and TLS protocols. These include information disclosure, data tampering, denial of service, acceptance of forged messages, unbounded memory growth, and use-after-free issues. Red Hat has issued an important security advisory providing updates to address these vulnerabilities in Red Hat Enterprise Linux 10.0 Extended Update Support. Users are advised to apply the available updates to mitigate these issues.
AI Analysis
Technical Summary
The Red Hat security advisory addresses several vulnerabilities in OpenSSL, including CVE-2025-69418 (information disclosure and data tampering via low-level OCB encryption/decryption calls), CVE-2026-31790 (information disclosure from uninitialized memory via invalid RSA public key), CVE-2026-28390 (denial of service due to NULL pointer dereference in CMS EnvelopedData processing), CVE-2026-34182 (CMS AuthEnvelopedData processing may accept forged messages), CVE-2026-34183 (unbounded memory growth in QUIC PATH_CHALLENGE handler), CVE-2026-45445 (AES-OCB IV ignored on EVP_Cipher() path), and CVE-2026-45447 (heap use-after-free in PKCS7_verify()). These vulnerabilities affect OpenSSL packages in Red Hat Enterprise Linux 10.0 Extended Update Support across multiple architectures. The advisory provides updated packages to remediate these issues.
Potential Impact
The vulnerabilities collectively allow for information disclosure, data tampering, denial of service, acceptance of forged messages, unbounded memory consumption, and memory corruption. These impacts can compromise the confidentiality, integrity, and availability of systems using affected OpenSSL versions. The advisory rates the security impact as Important (high severity).
Mitigation Recommendations
Red Hat has released updated OpenSSL packages for Red Hat Enterprise Linux 10.0 Extended Update Support that address these vulnerabilities. Users should apply these official updates as detailed in the Red Hat advisory (https://access.redhat.com/articles/11258) to remediate the issues. No additional mitigation steps are indicated beyond applying the provided patches.
