Microsoft Visual Studio Products (April 2026)

The Microsoft Visual Studio Products are missing a security update. It is, therefore, affected by an information disclosure vulnerability: - It is possible to obtain a user's NTLM hash by tricking them into cloning a malicious repository, or checking out a malicious branch that accesses an...

Plonky3: The sponge construction used to get a hash function from a cryptographic permutation is not collision resistant for inputs of different lengths

Vulnerability Currently, when hashing, if the number of elements to hash is not a multiple of the rate, hashiter pads by elements of the current state. This means that it is possible to create iterators of different lengths which lead to an identical hashed state. Given a simple example using a...
