CRIME Attack Uses Compression Ratio of TLS Requests as Side Channel to Hijack Secure Sessions

The new attack on TLS developed by researchers Juliano Rizzo and Thai Duong takes advantage of an information leak in the compression ratio of TLS requests as a side channel to enable them to decrypt the requests made by the client to the server. This, in turn, allows them to grab the user’s logi...

New Attack Uses SSL/TLS Information Leak to Hijack HTTPS Sessions

There is a feature supported by the SSL/TLS encryption standard and used by most of the major browsers that leaks enough information about encrypted sessions to enable attackers decrypt users’ supposedly protected cookies and hijack their sessions. The researchers who developed the attack that...

GnuTLS TLS Record Application GenericBlockCipher Parsing Integer Overflow (CVE-2012-1573)

An integer overflow vulnerability has been reported in GnuTLS. The vulnerability is due to improper handling of certain fields during the decryption process. A remote attacker can exploit this vulnerability by sending a specially crafted TLS Application Data packet to the server. Successful...

CVE-2012-2146

CVE-2012-2146 affects Elixir up to at least 0.8.0, where Blowfish in CFB mode is used without a unique initialization vector (IV). This weak IV construction can enable context-dependent users to obtain sensitive information and potentially decrypt the database. The connected documents confirm the...

More Sophisticated DDoS Attack a New Threat to Apache Servers

A once flawed DDoS attack targeting the world’s most widely used Web servers has improved its cryptography and attack capabilities to become a more serious threat. MP-DDoser, also known as “IP-Killer,” uses a relatively new low-bandwidth, “asymmetrical” HTTP attack to inflict a denial-of-service...

SOL13607 - Hosts may generate weak RSA keys under low entropy conditions

A recent study, linked in the Supplemental Information section, has revealed that when a system generates new RSA keys under low-entropy conditions, such as during the first system boot, the resulting keys may not be cryptographically strong. During its first boot, the BIG-IP system generates...

Ubuntu 8.04 LTS / 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : openssl vulnerabilities (USN-1451-1)

Mind that signal

The pace of change in mobile spying applications is rapid. However, when it comes to intercepting phone calls in the field, phones that use the older 2G mobile communications standard are easier to crack. Often, organizations that want to carry out an attack will force a mobile device from 3G int...
