CVE-2020-7872

Code execution via malformed-file integer overflow

Published Jul 12, 2021 · Updated Aug 4, 2024

Integer overflow in HumanTalk DaviewIndy 8.98.7.0 and earlier allows attackers to execute arbitrary code via a malformed format file. The application mishandles integer arithmetic while parsing the crafted file, but the public record does not identify the affected parser or operation. Opening an attacker-supplied file is required, after which code executes in the user's application context.
