Local crash via oversized Finger destination input
Published Mar 26, 2026 · Updated Mar 26, 2026
Out-of-bounds write in MegaPing 1.0 allows local users to crash the application via an oversized Finger destination address. The Destination Address List field accepts an 8,000-byte string without enforcing the destination buffer limit, so Finger processing writes beyond the buffer. The attacker must run the desktop application, paste the payload into the field, and click Start; the demonstrated consequence is a process crash.
