Description
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to improper management of internal resources within the application when processing multiple WASM threads. When multiple WASM threads had a reference to a module, and were looking up exported functions, one WASM thread could have overwritten another's entry in a shared stub table. Successful exploitation of the vulnerability may allow an attacker to execute arbitrary code on the system.
