CVE-2022-37052Public exploitNetwork attack vector

Application crash via failed XRef allocation handling

Published Aug 22, 2023 · Updated Nov 3, 2025

Reachable assertion in Poppler 22.07.0 allows context-dependent attackers to crash pdfseparate with a crafted PDF file. During page separation, markObject does not handle a failed XRef::add allocation before Object::getString asserts that the returned object is a string. Supplying the file to pdfseparate is required; the resulting SIGABRT terminates that process without reported data disclosure or modification.
