Outer Ear Authentication

The insides of our ears are a mysterious place for most of us. It turns out, however, that there’s more going on in there than we expected. In a study presented at the IEEE Fourth International Conference on Biometrics in September of 2010, researchers used a shape-finding algorithm to determine ...

Cryptosystems Showing Signs of 'Wear and Tear'

SAN FRANCISCO– It’s been an interesting year in the cryptography world, with new attacks on several algorithms, continued problems with hash functions and the recent research on weak RSA keys. With all of that as a backdrop, some of the brightest minds in the field, gathered here for the RSA...

gnutls: unknown hash algorithm NULL pointer derefence [GNUTLS-SA-2006-2]

The gnutlsx509oid2macalgorithm function in lib/gnutlsalgorithms.c in GnuTLS before 1.4.2 allows remote attackers to cause a denial of service crash via a crafted X.509 certificate that uses a hash algorithm that is not supported by GnuTLS, which triggers a NULL pointer dereference...

What You Need to Know About the RSA Key Research

It’s always slightly disorienting and confusing when a story about something as esoteric as weak encryption keys produced by poor random number generators makes its way into the real world and begins scaring the citizens. This can lead to confusion and worry about whether everyone’s online bankin...

Ubuntu 8.04 LTS / 10.04 LTS / 10.10 / 11.04 / 11.10 : openssl vulnerabilities (USN-1357-1)

It was discovered that the elliptic curve cryptography ECC subsystem in OpenSSL, when using the Elliptic Curve Digital Signature Algorithm ECDSA for the ECDHEECDSA cipher suite, did not properly implement curves over binary fields. This could allow an attacker to determine private keys via a timi...

Cryptographers : Satellite phones vulnerable to eavesdropping

Cryptographers : Satellite phones vulnerable to eavesdropping Researchers at a German university claim to have cracked the algorithm that secures satellite phone transmissions. They have broken the encryption of the two main standards used to protect calls from satellite phones, giving them the...

SuSE 11.1 Security Update : glibc (SAT Patch Number 4944) (deprecated)

The implementation of the blowfish based password hashing method had a bug affecting passwords that contain 8bit characters e.g. umlauts. Affected passwords are potentially faster to crack via brute-force methods. CVE-2011-2483 SUSE's crypt implementation supports the blowfish password hashing...

CVE-2011-4354

OpenSSL vulnerability CVE-2011-4354 affects OpenSSL before 0.9.8h on 32-bit platforms, in the ECDH/ECDHE handshake with P-256 and P-384 curves, due to an incorrect modular reduction algorithm in bn_nist.c. This design flaw allows remote attackers to obtain the TLS server private key after multipl...

CVE-2011-4354

crypto/bn/bnnist.c in OpenSSL before 0.9.8h on 32-bit platforms, as used in stunnel and other products, in certain circumstances involving ECDH or ECDHE cipher suites, uses an incorrect modular reduction algorithm in its implementation of the P-256 and P-384 NIST elliptic curves, which allows...

MySQL Weak Hash Algorithm

The version of MySQL installed on the remote host is older than 4.1.1. As such, it reportedly uses a weak algorithm to hash the passwords. A attacker who can read the mysql.user table will be able to retrieve the plaintext passwords quickly by brute-force attack. C Tenable Network Security, Inc...
