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...

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...

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. This module requires Metasploit: https://metasploit.com/download Current source:...

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...
