syncthing: information leakage

This issue can affect RSA computations in crypto/rsa, which is used by crypto/tls. TLS servers on 32-bit systems could plausibly leak their RSA private key due to this issue. Other protocol implementations that create many RSA signatures could also be impacted in the same way. Specifically,...

NAT-PMP Security Vulnerability Affects 1.2M Routers

Vulnerabilities in embedded devices, in particular small office and home office routers, have been relentless. Another serious issue was discovered this week that affects more than 1.2 million such devices due to improper NAT-PMP protocol implementations, most of which run counter to the...

SSL 3.0 MITM Attack

A vulnerability affecting most implementations of SSL 3.0 has been discovered that allows an attacker to decrypt some encrypted contents under certain conditions CVE-2014-3566. The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which mak...

Microsoft Extends SHA-2, TLS Support for Windows

One by one, tech companies have been tossing aside the SHA-1 cryptographic algorithm like the unreliable collision-prone mess that it is. Microsoft was among the first to steer its customers away from SHA-1 and established an internal edict that its developers would no longer use it for...

Cryptography Expert Says, 'PGP Encryption is Fundamentally Broken, Time for PGP to Die'

A Senior cryptography expert has claimed multiple issues with PGP email encryption - an open source end-to-end encryption to secure email. Before continuing, I would like to clarify that covering this topic doesn't mean you should stop using PGP encryption, instead we are bringing to you what...

OpenSSL 0.9.x CBC Error Information Leakage Weakness

No description provided by source. source: http://www.securityfocus.com/bid/6884/info A side-channel attack against implementations of SSL exists that, through analysis of the timing of certain operations, can reveal sensitive information to an active adversary. This information leaked by...

OpenSSL Heartbleed Highlights Crypto Pitfalls

There is no shortage of bad advice online about crypto–or anything else, for that matter. And the recent mess involving the OpenSSL heartbleed vulnerability has brought out plenty of advice on building, implementing and repairing cryptosystems, but experts say that the fundamental truths about ho...

Extended Random Extension Made Cracking BSAFE Trivial

UPDATE: Known theoretical attacks against TLS using the troubled Dual EC random number generator— something an intelligence agency might try its hand at—are in reality a bit more challenging than we’ve been led to believe. The addition of the Extended Random extension to RSA Security’s BSAFE...
