Debian Security Advisory DSA 3417-1 (bouncycastle - security update)

Tibor Jager, Jorg Schwenk, and Juraj Somorovsky, from Horst Gortz Institute for IT Security, published a paper in ESORICS 2015 where they describe an invalid curve attack in Bouncy Castle Crypto, a Java library for cryptography. An attacker is able to recover private Elliptic Curve keys from...

Code injection

Cisco TelePresence Video Communication Server VCS X8.6 uses the same encryption key across different customers' installations, which makes it easier for local users to defeat cryptographic protection mechanisms by leveraging knowledge of a key from another installation, aka Bug ID CSCuw64516...

Private Messaging System: Vuvuzela

Vuvuzela is a messaging system that protects the privacy of message contents and message metadata. Users communicating through Vuvuzela do not reveal who they are talking to, even in the presence of powerful nation-state adversaries. Vuvuzela is the first system that provides strong metadata...

Updated python-cryptography packages fix security vulnerability

The OpenSSL backend prior to 1.0.2 made extensive use of assertions to check response codes where our tests could not trigger a failure. However, when Python is run with -O these asserts are optimized away. If a user ran Python with this flag and got an invalid response code this could result in...

Microsoft Considers Earlier SHA-1 Deprecation Deadline

Tech companies continue to back away from SHA-1 like it’s an infectious disease. Microsoft, which already had plans to deprecate the crusty cryptographic algorithm by the start of 2017, decided this week to move up that deadline six months. The company said it’s considering whether it will start...

Cryptographers Concerned Over NSA's Deprecation of ECC

The National Security Agency has long cuddled up to Elliptic Curve Cryptography, swaying standards bodies away from RSA crypto and toward ECC in the late 1990s, as well as recommending it as a strong enough solution for sensitive government agencies to use in guarding their biggest secrets. In...
