Description

Dell EMC Open Manage System Administrator (OMSA) versions prior to 9.3.0 contain an Improper Range Header Processing Vulnerability. A remote unauthenticated attacker may send crafted requests with overlapping ranges to cause the application to compress each of the requested bytes, resulting in a crash due to excessive memory consumption and preventing users from accessing the system.
