Denial Of Service (DoS)

Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third-party, the Key Distribution Center KDC. An uninitialized pointer use flaw was found in the way the MIT Kerberos KDC handled initial...

Updated python-gnupg packages fix security vulnerability

When symmetric encryption is used, data can be injected through the passphrase property of the gnupg.GPG.encrypt and gnupg.GPG.decrypt methods. The supplied passphrase is not validated for newlines, and the library passes --passphrase-fd=0 to the gpg executable, which expects the passphrase on th...

Two NSA Algorithms Rejected by the ISO

The ISO has rejected two symmetric encryption algorithms: SIMON and SPECK. These algorithms were both designed by the NSA and made public in 2013. They are optimized for small and low-cost processors like IoT devices. The risk of using NSA-designed ciphers, of course, is that they include...

Encryption 101: How to break encryption

Continuing on in our Encryption 101 series, where we gave a malware analyst's primer on encryption and demonstrated encryption techniques using ShiOne ransomware, we now look at what it takes to break an encryption. In order for something as powerful as encryption to break, there needs to be some...

Authentication flaw

s2k.js in OpenPGP.js will decrypt arbitrary messages regardless of passphrase for crafted PGP keys which allows remote attackers to bypass authentication if message decryption is used as an authentication mechanism via a crafted symmetrically encrypted PGP message...

Unverifiable Symmetric Encryption

spring-cloud-config has a flaw which allows malicious manipulation of symmetric encryptions. The vulnerability exists because its default symmetric encryption does not use a Message Authentication Code MAC to verify the authenticity of encrypted message...
