Technical details
The MAT decoder fails to release allocated memory in a specific error path (CWE-401), allowing repeated small memory leaks when processing crafted MAT files. An attacker can trigger this error path remotely by supplying malicious MAT files over the network with no authentication or user interaction required, causing the vulnerable process to gradually exhaust available memory.
