Application crash via overlong Whois domain input
Published Feb 12, 2026 · Updated Feb 12, 2026
Stack-based buffer overflow in ComcSoft iNetTools 8.20 allows attackers to crash the iOS application through Whois input. The Whois Domain Name handler writes a crafted 98-character value beyond its stack allocation, terminating the process. Exploitation requires an iPhone or iPad user to paste crafted clipboard content into Whois and start the query; the demonstrated consequence is an application crash.
