CVE-2023-29146 – Malwarebytes Endpoint Agents – Hash collision
SUMMARY:
The utility functions used, by Malwarebytes Endpoint Agent for Linux before 1.1.64 and Malwarebytes for Windows v5 having an update package version < 1.0.106875 , for calculating a cryptographic hash of data bytes, truncate the hashed data if it exceeds 4GB. This could lead to colliding hash values for two different strings in some scenarios and detection misses.
