Padding Oracle Crypto Research Prompts Confusion, Dissenting Opinions on Severity

Few things tend to spark debates and controversy in the security community like a new piece of cryptographic research. The paper by a group of academic researchers on an improvement to a padding oracle attack on certain hardware security tokens publicized this week is no different, with RSA...

FreeBSD : FreeBSD -- OpenSSL multiple vulnerabilities (2ae114de-c064-11e1-b5e0-000c299b62e1)

Problem description : OpenSSL fails to clear the bytes used as block cipher padding in SSL 3.0 records when operating as a client or a server that accept SSL 3.0 handshakes. As a result, in each record, up to 15 bytes of uninitialized memory may be sent, encrypted, to the SSL peer. This could...

Experts Say Attack on Crypto Tokens is Serious, But Not Catastrophic

A group of international academic researchers has made a major advance in the efficiency of a known cryptographic attack on some kinds of crypto hardware, enabling them to extract sensitive keys from tokens such as RSA SecurID and Aladdin eToken devices within 20 minutes. However, experts say tha...

Microsoft Releases Automatic Updater for Certificate Revocation Lists, Plans to Invalidate Short RSA Keys

As part of its response to the Flame malware and its usage of a forged Microsoft certificate to sign malicious files, Microsoft has changed the way that Windows handles certificates, releasing an automatic updater function that will recognize and flag untrusted certificates. The new functionality...

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...
