CVE-2023-29146 — HIGH (8.2)

Vulnerability Description

The utility functions used by Malwarebytes EDR 1.0.11 on Linux for calculating a cryptographic hash of data bytes truncate the hashed data if it exceeds 4GB. This leads to an integer wrap-around if the data is larger than the maximum unsigned integer value (32-bit). Attackers could create a colliding hash value for two different strings by attaching 4GB of data to a string that is less than 4GB in size.
