New Version of OpenSSL Fixes Six Flaws

A new version of the OpenSSL package has been released, fixing six vulnerabilities, including a plaintext recovery attack on the DTLS implementation. There are two other cryptographic flaws fixed in OpenSSL 1.0.0f, and a few other less-serious problems. The most problematic of the vulnerabilities...

OpenSSL 0.9.8 < 0.9.8s / 1.x < 1.0.0f Multiple Vulnerabilities

CVE-2011-4108

The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack...

OpenSSL 1.0.0 < 1.0.0-beta2 DoS

According to its banner, the remote server is running a version of OpenSSL 1.0.0 prior to 1.0.0 beta 2. A remote attacker can crash the server by sending an out-of-sequence DTLS handshake message. C Tenable Network Security, Inc. include"compat.inc"; if description scriptid17768;...

OpenSSL < 0.9.8l Multiple Vulnerabilities

According to its banner, the remote server is running a version of OpenSSL that is earlier than 0.9.8l. As such, it may be affected by multiple vulnerabilities : - A remote attacker could crash the server by sending malformed ASN.1 data. This flaw only affects some architectures, Win64 and other...

Vulnerability in OpenSSL - DTLS DoS attack

A flaw in the fix to CVE-2011-4108 can be exploited in a denial of service attack. Only DTLS applications are affected. Found by Antonio Martin...

Vulnerability in OpenSSL - DTLS Plaintext Recovery Attack

OpenSSL was susceptable an extension of the Vaudenay padding oracle attack on CBC mode encryption which enables an efficient plaintext recovery attack against the OpenSSL implementation of DTLS by exploiting timing differences arising during decryption processing. Found by Nadhem Alfardan and Ken...

OpenSSL 0.9.8 < 0.9.8i Vulnerability

The version of OpenSSL installed on the remote host is prior to 0.9.8i. It is, therefore, affected by a vulnerability as referenced in the 0.9.8i advisory. - ssl/s3pkt.c in OpenSSL before 0.9.8i allows remote attackers to cause a denial of service NULL pointer dereference and daemon crash via a...

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:...
