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...

CVE-2016-2179

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 segmentation fault in dtls1_get_record

A NULL pointer dereference flaw was found in the DTLS implementation of OpenSSL. A remote attacker could send a specially crafted DTLS message, which would cause an OpenSSL server to crash...

LibreSSL Double Release Vulnerability

LibreSSL is a fork of the OpenSSL cryptographic software library developed by the OpenBSD project and an open source implementation of the Secure Sockets Layer SSL and Transport Layer Security TLS protocols. A double-release vulnerability exists in the 'sslparseclienthellousesrtpext' function in...

openssl: DTLS packet processing double free

A flaw was discovered in the way OpenSSL handled DTLS packets. A remote attacker could use this flaw to cause a DTLS server or client using OpenSSL to crash or use excessive amounts of memory...

openssl: DoS when sending invalid DTLS handshake

A denial of service flaw was found in the way OpenSSL handled certain DTLS ServerHello requests. A specially crafted DTLS handshake packet could cause a DTLS client using OpenSSL to crash...

openssl: DTLS memory exhaustion

A flaw was discovered in the way OpenSSL handled DTLS packets. A remote attacker could use this flaw to cause a DTLS server or client using OpenSSL to crash or use excessive amounts of memory...

OpenSSL DTLS Fragment Buffer Overflow DoS Exploit

This module performs a Denial of Service Attack against Datagram TLS in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h. This occurs when a DTLS ClientHello message has multiple fragments and the fragment lengths of later fragments are larger than that of the first, a buffer...

openssl: DoS when sending invalid DTLS handshake

A denial of service flaw was found in the way OpenSSL handled certain DTLS ServerHello requests. A specially crafted DTLS handshake packet could cause a DTLS client using OpenSSL to crash...

OpenSSL DTLS Fragment Buffer Overflow DoS

This module performs a Denial of Service Attack against Datagram TLS in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h. This occurs when a DTLS ClientHello message has multiple fragments and the fragment lengths of later fragments are larger than that of the first, a buffer...

Theoretical Lucky Thirteen TLS Attacks Could Turn Practical

For now, the Lucky Thirteen attacks described in a paper last week by researchers at Royal Holloway, University of London, are largely theoretical. But the potential exists to adapt techniques used in the BEAST attacks against TLS/SSL to improve the feasibility of Lucky Thirteen, a researcher sai...

DEBIAN-CVE-2013-1586

The fragmentsettotlen function in epan/reassemble.c in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 does not properly determine the length of a reassembled packet for the DTLS dissector, which allows remote attackers to cause a denial of service application crash via a malformed packet...

CentOS 5 : openssl (CESA-2009:1335)

Updated openssl packages that fix several security issues, various bugs, and add enhancements are now available for Red Hat Enterprise Linux 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team. OpenSSL is a toolkit that implements the Secure...

RedHat Security Advisory RHSA-2009:1335

The remote host is missing updates announced in advisory RHSA-2009:1335. OpenSSL is a toolkit that implements the Secure Sockets Layer SSL v2/v3 and Transport Layer Security TLS v1 protocols, as well as a full-strength general purpose cryptography library. Datagram TLS DTLS is a protocol based on...

OpenSSL: DTLS pointer use-after-free flaw (DoS)

Use-after-free vulnerability in the dtls1retrievebufferedfragment function in ssl/d1both.c in OpenSSL 1.0.0 Beta 2 allows remote attackers to cause a denial of service openssl sclient crash and possibly have unspecified other impact via a DTLS packet, as demonstrated by a packet from a server tha...

OpenSSL DTLS ChangeCipherSpec Remote DoS

This module performs a Denial of Service Attack against Datagram TLS in OpenSSL version 0.9.8i and earlier. OpenSSL crashes under these versions when it receives a ChangeCipherspec Datagram before a ClientHello. Module Options msf use auxiliary/dos/ssl/dtls/changecipherspec msf...
