CVE-2020-10222Public exploitNetwork attack vector

Process-data disclosure and crash via crafted PDF

Published Mar 8, 2020 · Updated Aug 4, 2024

Heap corruption in npdf.dll in Nitro Pro before 13.13.2.242 allows remote attackers to corrupt memory via a crafted PDF document. The public record identifies nitro::get_property+2381 as the faulting location but does not disclose the malformed property or erroneous memory operation. Opening the file is required, and successful triggering can expose process data or interrupt the application without modifying data.
