OpenSSL DTLS Fragment Out-Of-Bounds Write Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of OpenSSL. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of DTLS packets. The issue lies in the assumption that all fragments specify the...

Vulnerability in OpenSSL - DTLS recursion flaw

By sending an invalid DTLS handshake to an OpenSSL DTLS client the code can be made to recurse eventually crashing in a DoS attack. Only applications using OpenSSL as a DTLS client are affected...

Vulnerability in OpenSSL - DTLS invalid fragment vulnerability

A buffer overrun attack can be triggered by sending invalid DTLS fragments to an OpenSSL DTLS client or server. This is potentially exploitable to run arbitrary code on a vulnerable client or server. Only applications using OpenSSL as a DTLS client or server affected...

OpenSSL -- multiple vulnerabilities

The OpenSSL Project reports: An attacker using a carefully crafted handshake can force the use of weak keying material in OpenSSL SSL/TLS clients and servers. This can be exploited by a Man-in-the-middle MITM attack where the attacker can decrypt and modify traffic from the attacked client and...

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...

OpenSSL DTLS Invalid Fragment Remote Code Execution (CVE-2014-0195)

A remote code execution vulnerability exists in OpenSSL. The vulnerability is due to an error when handling fragmented DTLS handshake messages. Successful exploitation can create a denial of service condition and may allow execution of arbitrary code within the context of the process using OpenSS...

Debian Security Advisory DSA 2950-1 (openssl - security update)

Multiple vulnerabilities have been discovered in OpenSSL: CVE-2014-0195 Jueri Aedla discovered that a buffer overflow in processing DTLS fragments could lead to the execution of arbitrary code or denial of service. CVE-2014-0221 Imre Rad discovered the processing of DTLS hello packets is...
