Gobbler Merkle tree vulnerable to second preimage attack

Lines of code Vulnerability details Impact The Merkle tree is vulnerable to a second preimage attack due to the fact that there is no prefix to distinguish between leaves an intermediate nodes Proof of Concept There are no prefixes added to the values in MerkleProofLib and none included in what's...

SLOTH Collisions Attacks Against SHA-1, MD5 in TLS, IKE, SSH

If you’re hanging on to the theory that collision attacks against SHA-1 and MD5 aren’t yet practical, two researchers from INRIA, the French Institute for Research in Computer Science and Automation, have demonstrated new attacks that raise the urgency to move away from these broken cryptographic...

Elevating Privileges Via Windows Installers

There’s an odd bit of behavior that some Windows systems will exhibit when certain kinds of installers are launched, automatically elevating the privileges of the installer process to system-level privileges. In theory, the issue shouldn’t be exploitable because at one point in the process the...
