OpenVPN: denial of service

OpenVPN team reports: OpenVPN 2.x allows attackers to potentially cause a denial of service against the control channel reliability layer, either by driving the reliable TLS retransmission timeout to grow without bound, or by sending acknowledgements for packets that cannot be outstanding...

crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages

A flaw was found in the crypto/tls package, part of golang. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service DoS...

io.netty/netty-handler: Netty: TLS hostname verification bypass via OpenSSL client path misconfiguration

A flaw was found in Netty io.netty:netty-handler. When using the SslProvider.OPENSSL client path with a plain X509TrustManager and without Unsafe-based trust-manager wrapping Java 25+, TLS hostname verification is disabled. This misconfiguration allows a man-in-the-middle attacker to present a...

org.apache.httpcomponents.client5/httpclient5: Apache HttpComponents Client: Server impersonation via improper TLS hostname verification

A flaw was found in the asynchronous version of Apache HttpComponents Client. This improper Transport Layer Security TLS hostname verification vulnerability allows a remote attacker to intercept and modify network traffic. By presenting a valid certificate for a different domain, an attacker can...
