GHSA-P72G-CGH9-GHJG Failing DTLS handshakes may cause throttling to block processing of records

Impact Failing handshakes didn't cleanup counters for throttling. In consequence the threshold may get reached and will not be released again. The results in permanently dropping records. The issues was reported for certificate based handshakes, but it can't be excluded, that this happens also fo...

CVE-2022-34293

UBUNTU-CVE-2022-35409

An issue was discovered in Mbed TLS before 2.28.1 and 3.x before 3.2.0. In some configurations, an unauthenticated attacker can send an invalid ClientHello message to a DTLS server that causes a heap-based buffer over-read of up to 255 bytes. This can cause a server crash or possibly information...

UBUNTU-CVE-2022-29222

Pion DTLS is a Go implementation of Datagram Transport Layer Security. Prior to version 2.1.5, a DTLS Client could provide a Certificate that it doesn't posses the private key for and Pion DTLS wouldn't reject it. This issue affects users that are using Client certificates only. The connection...

UBUNTU-CVE-2022-29189

Pion DTLS is a Go implementation of Datagram Transport Layer Security. Prior to version 2.1.4, a buffer that was used for inbound network traffic had no upper limit. Pion DTLS would buffer all network traffic from the remote user until the handshake completes or timed out. An attacker could explo...

The vulnerability in the implementation of the DTLS protocol by the OpenSSL library, which allows a hacker to cause a service failure.

The vulnerability of the DTLS protocol implementation in the OpenSSL library is related to resource management errors. Exploiting this vulnerability can allow a malicious actor to cause service failures remotely...

californium-core: DTLS - DoS vulnerability for certificate based handshakes

A flaw was found in californium. The certificate based x509 and RPK DTLS handshakes fails due to the DTLS server side being set to a wrong internal state by a previous certificate based DTLS handshake failure with TLS parameter mismatch. The highest threat from this vulnerability is to system...

Fixed an issue in Citrix ADC and Citrix Gateway

Citrix has fixed an issue in ADC and Gateway which can lead to denial-of-service attacks. A malicious party could potentially potentially misuse DTLS to cause a Denial-of-Service. Abuse can only occur when DTLS is enabled. Citrix reports that limited scale attacks are currently being reported whi...

MatrixSSL Invalid Pointer Release Vulnerability

MatrixSSL is an embedded, open source SSLv3 stack designed for small applications and devices. An invalid pointer release vulnerability exists in the DTLS server in versions prior to MatrixSSL 4.2.2 Open. An attacker could exploit this vulnerability via specially crafted incoming network messages...

Inside Secure MatrixSSL 缓冲区错误漏洞

MatrixSSL is an embedded, open source SSLv3 stack designed for small applications and devices. An invalid pointer release vulnerability exists in the DTLS server in versions prior to MatrixSSL 4.2.2 Open.

CVE-2020-24585

Overview An issue was discovered in the DTLS handshake implementation in wolfSSL before 4.5.0. Clear DTLS applicationdata messages in epoch 0 do not produce an out-of-order error. Instead, these messages are returned to the application. Remediation Upgrade wolfssl to version 4.5.0 or higher...

The vulnerability of the statem/statemdtls.c component in the OpenSSL library, which allows a hacker to cause a service failure.

The vulnerability of the statem/statemdtls.c component in the OpenSSL library is related to a resource management mechanism error. Exploiting this vulnerability could allow an attacker to cause service interruptions through a specially created DTLS message...

gnutls: DTLS client hello contains a random value of all zeroes

A cryptographic weakness was found in the way DLTS implementation of GnuTLS, used zeros in place of random numbers. This flaw can break the security guarantee of the DTLS protocol...

An update is available that adds support for DTLS in Windows 7 SP1 and Windows Server 2008 R2 SP1

An update is available that adds support for DTLS in Windows 7 SP1 and Windows Server 2008 R2 SP1 Summary What is DTLS? The DTLS protocol provides communications privacy. The protocol allows client and server applications to communicate in a way that is designed to prevent eavesdropping, tamperin...

ALPINE-CVE-2020-11501

GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 2018-07-16 because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks...
