CVE-2016-2179

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 allows remote attackers to cause a denial of service memory consumption by maintaining many crafted DTLS sessions simultaneously, related to...

CVE-2016-2179

OpenSSL CVE-2016-2179: The DTLS implementation could exhaust memory by accepting many crafted DTLS sessions due to unprocessed, out-of-order handshake messages. This memory-DoS vectors arises from DTLS queue handling in d1_lib.c, statem_dtls.c, statem_lib.c, and statem_srvr.c. Public advisories (...

CVE-2016-2181

A flaw was found in the Datagram TLS DTLS replay protection implementation in OpenSSL. A remote attacker could possibly use this flaw to make a DTLS server using OpenSSL to reject further packets sent from a DTLS client over an established DTLS connection...

Vulnerability in OpenSSL - DTLS buffered message DoS

In a DTLS connection where handshake messages are delivered out-of-order those messages that OpenSSL is not yet ready to process will be buffered for later use. Under certain circumstances, a flaw in the logic means that those messages do not get removed from the buffer even though the handshake...

Vulnerability in OpenSSL - DTLS replay protection DoS

A flaw in the DTLS replay attack protection mechanism means that records that arrive for future epochs update the replay protection “window” before the MAC for the record has been validated. This could be exploited by an attacker by sending a record for the next epoch which does not have to decry...

Vulnerability of Firefox and Firefox ESR browsers, allowing attackers to execute arbitrary code

The vulnerability of WebRTC sockets in Firefox and Firefox ESR browsers relates to the use of memory after it is freed. Exploiting this vulnerability allows a malicious actor to execute arbitrary code by using incorrect free operations on DTLS objects during the termination of a WebRTC session...

Design/Logic Flaw

Use-after-free vulnerability in the WebRTC socket thread in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 allows remote attackers to execute arbitrary code by leveraging incorrect free operations on DTLS objects during the shutdown of a WebRTC session...

Use-after-free in DTLS during WebRTC session shutdown — Mozilla

Security researcher Looben Yang reported a use-after-free vulnerability in WebRTC. This occurs during WebRTC session shutdown when DTLS objects in memory are freed while still actively in use. This results in a potentially exploitable crash...

The vulnerability of Cisco ASA software allows a malicious individual to execute arbitrary code.

The vulnerability exists in the function dtls1reassemblefragment in d1both.c in OpenSSL, due to incorrect checking of the length of fragments in DTLS ClientHello messages. Exploiting this vulnerability allows an attacker to execute arbitrary code or cause a service failure buffer overflow and...

The vulnerability of the OpenSSL software allows a malicious attacker to compromise the confidentiality and accessibility of protected information.

A memory leak in the d1srtp.c file of the DTLS SRTP extension in OpenSSL allows malicious actors operating remotely to trigger a service failure excessive memory consumption through specially crafted negotiation messages...
