Idira Endpoint Privilege Manager Agent versions prior to 26.5 exhibit improper access control within high-privileged agent components. A local, low-privileged attacker could exploit this by manipulating an internal communication mechanism or file operation. Under specific circumstances, this could potentially allow the attacker to bypass permission restrictions and execute unauthorized local actio…

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…
