| Doc Text: |
A memory exposure flaw has been discovered in NetSurf. In the `_dom_event_initialise` function, several JavaScript-accessible fields of the dom_event structure are left uninitialized. It appears to leak the lower four bytes of a valid heap address on 64-bit systems. While likely not exploitable on its own, this bug may serve as a partial information leak primitive for other exploits.
