Vulnerability in OpenSSL - OpenSSL TLS protocol downgrade attack

A flaw in the OpenSSL SSL/TLS server code causes the server to negotiate TLS 1.0 instead of higher protocol versions when the ClientHello message is badly fragmented. This allows a man-in-the-middle attacker to force a downgrade to TLS 1.0 even if both the server and the client support a higher...

AIX OpenSSL Advisory : openssl_advisory2.asc

The version of OpenSSL running on the remote host is affected by the following vulnerabilities : - ssl/t1lib.c in OpenSSL 0.9.8h through 0.9.8q and 1.0.0 through 1.0.0c allows remote attackers to cause a denial of service crash, and possibly obtain sensitive information in applications that use...

ESXi 5.0 < Build 912577 Multiple Vulnerabilities (remote check)

The remote VMware ESXi 5.0 host is affected by Multiple Vulnerabilities : - An integer overflow condition exists in the tzfileread function in the glibc library.

DEBIAN-CVE-2013-1654

Puppet 2.7.x before 2.7.21 and 3.1.x before 3.1.1, and Puppet Enterprise 2.7.x before 2.7.2, does not properly negotiate the SSL protocol between client and master, which allows remote attackers to conduct SSLv2 downgrade attacks against SSLv3 sessions via unspecified vectors...

CVE-2013-1654

CVE-2013-1654 affects Puppet 2.7.x prior to 2.7.21, Puppet 3.1.x prior to 3.1.1, and Puppet Enterprise 2.7.x prior to 2.7.2. The issue arises from how SSL protocol negotiation occurs between client and master, enabling remote attackers to perform SSLv2 downgrade attacks against SSLv3 sessions via...

Design/Logic Flaw

Adobe Shockwave Player through 11.6.8.638 allows remote attackers to trigger installation of a Shockwave Player 10.4.0.025 compatibility feature via a crafted HTML document that references Shockwave content with a certain compatibility parameter, related to a "downgrading" attack...

Windows NetLM Downgrade Attack

This module changes the system LmCompatibilityLevel registry value to enable sending LM challenge hashes and initiates a SMB connection to the host specified in the SMBHOST module option. If an SMB server is listening, it will receive the NetLM hashes for the session user. This module requires...
