Summary

In Malwarebytes EDR 1.0.11 on Linux, utility functions for calculating cryptographic hashes truncate data exceeding 4GB, causing an integer wrap-around. An attacker can create a hash collision for two different strings by appending 4GB of data to a shorter string.

Risk Assessment

An attacker could exploit this vulnerability to spoof data integrity, potentially bypassing threat detection mechanisms.

Recommendation

It is recommended to update Malwarebytes EDR to a version containing a fix for the data truncation issue.

Original NVD description (English source)

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.
