Описание

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: OpenSSL: Denial of Service via unbounded memory growth in QUIC server (CVE-2026-14456)

• openssl: QUIC server may trigger double free when processing INITIAL packet (CVE-2026-18798)

• openssl: heap buffer overflow in CMS key unwrapping (CVE-2026-63072)

• openssl: invalid pointer dereference in CMP server via crafted protectionAlg (CVE-2026-63076)

• openssl: RPK server signature algorithm selection can dereference a missing certificate (CVE-2026-14457)

• openssl: excessive memory use buffering DTLS records for a future epoch (CVE-2026-54874)

• openssl: untrusted sender DN used as format string in CMP response validation (CVE-2026-63073)

• openssl: CMP indefinite cache growth of ExtraCerts (CVE-2026-63074)

• openssl: QUIC ACK-only packet retention can cause memory exhaustion (CVE-2026-63075)

Bug Fix(es) and Enhancement(s):

• openssl: HollowByte remote memory-exhaustion DoS fix may be missing [Rocky Linux 9.8.z] (JIRA:Rocky Linux-232828)
