CVE-2021-34433

In Eclipse Californium version 2.0.0 to 2.6.4 and 3.0.0-M1 to 3.0.0-M3, the certificate based x509 and RPK DTLS handshakes accidentally succeeds without verifying the server side's signature on the client side, if that signature is not included in the server's ServerKeyExchange...

CVE-2012-4566

The DTLS support in radsecproxy before 1.6.2 does not properly verify certificates when there are configuration blocks with CA settings that are unrelated to the block being used for verifying the certificate chain, which might allow remote attackers to bypass intended access restrictions and spo...

CVE-2013-6686

The SSL VPN implementation in Cisco IOS 15.31T2 and earlier allows remote authenticated users to cause a denial of service interface queue wedge via crafted DTLS packets in an SSL session, aka Bug IDs CSCuh97409 and CSCud90568...

Double free vulnerability in OpenConnect before 1.40 might allow remote AnyConnect SSL VPN servers to cause a denial of service application crash or possibly have unspecified other impact via a crafted DTLS Cipher option during a reconnect operation...

Security Bulletin: IBM Watson Speech Services Cartridge is vulnerable to a man-in-the-middle attack in OpenSSL [CVE-2024-12797]

Summary IBM Watson Speech Services Cartridge is vulnerable to a man-in-the-middle attack in OpenSSL, caused by a failure to abort TLS/DTLS handshakes in RFC7250 Raw Public Key RPK authentication CVE-2024-12797. OpenSSL is used by our Speech runtimes. This vulnerabilitiy has been addressed. Please...

Siemens SCALANCE X-200RNA Switch Devices Incorrect Calculation (CVE-2016-2181)

The Anti-Replay feature in the DTLS implementation in OpenSSL before 1.1.0 mishandles early use of a new epoch number in conjunction with a large sequence number, which allows remote attackers to cause a denial of service false-positive packet drops via spoofed DTLS records, related to reclayerd1...

Siemens SCALANCE X-200RNA Switch Devices Improper Input Validation (CVE-2015-0207)

The dtls1listen function in d1lib.c in OpenSSL 1.0.2 before 1.0.2a does not properly isolate the state information of independent data streams, which allows remote attackers to cause a denial of service application crash via crafted DTLS traffic, as demonstrated by DTLS 1.0 traffic to a DTLS 1.2...

Linux Distros Unpatched Vulnerability : CVE-2023-6937

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - wolfSSL prior to 5.6.6 did not check that messages in one DTLS record do not span key boundaries. As a result, it was possible to combine DTLS messages using...

Linux Distros Unpatched Vulnerability : CVE-2016-2179

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The DTLS implementation in OpenSSL before 1.1.0 does not properly restrict the lifetime of queue entries associated with unused out-of-order messages, which...

ROS-20250226-16

SSLVERIFYPEER mode vulnerability in the OpenSSL cryptographic library is related to the lack of a mechanism of to notify the user when a communication session is established. Exploitation of the vulnerability could allow an attacker acting remotely to realize a man-in-the-middle attack during a...

AZL-56774 CVE-2024-12797 affecting package openssl for versions less than 3.3.3-1

Issue summary: Clients using RFC7250 Raw Public Keys RPKs to authenticate a server may fail to notice that the server was not authenticated, because handshakes don't abort as expected when the SSLVERIFYPEER verification mode is set. Impact summary: TLS and DTLS connections using raw public keys m...

CVE-2022-29190

Pion DTLS is a Go implementation of Datagram Transport Layer Security. Prior to version 2.1.4, an attacker can send packets that sends Pion DTLS into an infinite loop when processing. Version 2.1.4 contains a patch for this issue. There are currently no known workarounds available...
