SUSE 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...

OpenSSL: Invalid free in DTLS

An invalid-free flaw was found in the way OpenSSL handled certain DTLS handshake messages. A malicious DTLS client or server could send a specially crafted message to the peer, which could cause the application to crash or potentially result in arbitrary code execution...

openssl: DTLS memory exhaustion DoS when messages are not removed from fragment buffer

It was discovered that the Datagram TLS DTLS implementation could fail to release memory in certain cases. A malicious DTLS client could cause a DTLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory...

openssl: DTLS replay protection bypass allows DoS against DTLS connection

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...

ALPINE-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...
