NetAware 1.20 contains a buffer overflow vulnerability in the User Blocking feature that allows local attackers to crash the application by supplying oversized input. Attackers can paste a malicious buffer of 512 bytes into the 'Add a website or keyword to be filtered' field and trigger a crash when removing the created block.
