Missing SNI/ALPN binding on stateful session-ID resumption, which previously skipped the binding check performed for ticket-based resumption. A cached session could be resumed under a different SNI/ALPN than originally negotiated and, where client-authentication policy differs across virtual host...

Astra Linux – Vulnerability in vsftpd

ALPACA is an application layer protocol content confusion attack, exploiting TLS servers that implement different protocols but use compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker, who has access to the victim’s traffic at the TCP/IP layer, can redirect...

Defense in depth for autonomous AI agents

Designing Secure Autonomous AI Agents with Defense in Depth AI agents are moving beyond assistance and into action. Instead of generating content, they invoke tools, modify data, trigger workflows, and operate across systems with increasing autonomy. This shift changes the security problem...

Defending consumer web properties against modern DDoS attacks

If you own, create, or maintain online services and web portals, you’re probably aware of the dramatic upswing in DDoS attacks on your domains. AI has democratized tooling not just for us but for threat actors as well. DDoS in this era has extended from simple bandwidth saturation to sophisticate...

Issue summary: Calling the OpenSSL API function SSLselectnextproto with an empty supported client protocols buffer may cause a crash or memory contents to be sent to the peer. Impact summary: A buffer overread can have a range of potential consequences such as unexpected application beahviour or ...

nodejs: Nodejs denial of service

A flaw in Node.js TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback are in use. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling paths tlsClientError and error, causing either immediate...

crypto/tls: go crypto/tls ALPN negotiation error contains attacker controlled information

The crypto/tls conn.Handshake method returns an error on the server-side when ALPN negotation fails which can contain arbitrary attacker controlled information provided by the client-side of the connection which is not escaped. This affects programs which log these errors without any additional...
