tls 1.3

A subtle but consequential TLS 1.3 implementation issue is circulating under the label CVE-2026-2673 — described as an OpenSSL behavior in which a TLS 1.3 server can select an unexpected key‑agreement group (and even place an unsupported group into the HelloRetryRequest/key_share exchange)...

A malformed TLS 1.3 packet can crash a wolfSSL server or force it to read memory outside its bounds — a vulnerability tracked as CVE-2024-0901 that was disclosed in early 2024 and fixed by wolfSSL in the 5.7.x release series. This issue is not a local misconfiguration or an edge-case...

CVE‑2024‑2511 exposed a surprising — and at first glance narrowly scoped — weakness in OpenSSL’s TLSv1.3 session handling: certain non‑default server configurations can cause the session cache to stop flushing and grow without bound, allowing a remote actor to force resource exhaustion and a...

wolfSSL has patched a denial‑of‑service weakness in its TLS 1.3 handshake code after researchers discovered that a specially crafted ClientHello containing duplicate KeyShareEntry values for the same group can force excessive CPU and memory use during ClientHello processing, leading to...

Microsoft is routing Exchange ActiveSync Certificate‑Based Authentication (CBA) traffic to new, dedicated CBA endpoints by cloud region — a seemingly small change with important operational and security consequences for any organization that terminates, inspects, or filters ActiveSync traffic at...

SMB over QUIC is the most promising evolution in file sharing since SMB 3.x—promising VPN-less, always-encrypted file access, faster connection setup, seamless roaming, and resilience on flaky networks—but the technology is not yet a drop-in replacement for TCP-based SMB in most production...

Windows developers and administrators who depend on client-certificate (mTLS) workflows will need to keep using workarounds: a structural limitation introduced by TLS 1.3 and the way Windows handles TLS in kernel (http.sys / Schannel) means IIS Express on Windows 11 cannot reliably request a...

Microsoft’s first Release Candidate (RC0) for SQL Server 2025 is here, and it’s more than a stability checkpoint—it’s a statement of direction that blends built-in AI, developer‑friendly T‑SQL, and secure‑by‑default networking into a single, on‑premises database platform that looks and feels...

Microsoft’s Release Candidate 0 for SQL Server 2025 marks a decisive step toward a modern, AI‑first database platform — with official Ubuntu 24.04 support for development and testing, TLS 1.3 enabled by default, and a broad slate of performance and AI features that aim to reshape how enterprises...

Microsoft has pushed the first public Release Candidate (RC0) of SQL Server 2025 into preview with two headline changes that matter to every Windows-centric IT team experimenting with Linux-first development: official Ubuntu 24.04 support for dev/test scenarios and TLS 1.3 enabled by default...

Microsoft’s public roadmap for a quantum‑safe future is no longer a research manifesto: it’s a multi‑year engineering and procurement plan that maps how SymCrypt, Windows, Azure, Microsoft 365 and silicon will evolve to resist the cryptanalytic power of future quantum computers. The company has...

Siemens has published a security advisory for Opcenter Quality that maps seven distinct CVEs affecting SmartClient modules (Opcenter QL Home), SOA Audit and SOA Cockpit — the vulnerabilities range from incorrect authorization and insufficient session expiration to support for legacy TLS...

Microsoft's relentless drive to keep its Edge browser competitive has seen another significant leap with the arrival of Edge Beta 138.0.3351.14, which introduces a compelling mix of AI-powered features, usability tweaks, and enterprise-grade policy controls. This update isn't just a routine...

Transport Layer Security (TLS) is at the heart of secure communications on the modern internet, defending data in transit from eavesdropping, tampering, and other threats. For organizations relying on Windows Server to deliver web applications or manage infrastructure, keeping TLS protocols up...

Windows Server 2025 emerges as a milestone in enterprise computing, signaling not just another incremental update but a bold leap in Microsoft’s server operating system. For IT professionals, business leaders, and tech-savvy administrators, assessing the scope and value of this Long-Term...

In an era where the cloud often hogs the limelight, Windows Server 2025 reminds us that local, on-premises solutions still offer rock-solid security and reliability. Far from being the relic of a bygone era, Active Directory (AD) remains a cornerstone of network infrastructure. The latest...

Performance and security matter to everyone. Better page load performance improves the user’s experience and influences their choice over which web pages to use. At the same time, users just expect their browsing experience to be secure and private. With TCP Fast Open, TLS False Start, and TLS...
