lopdf versions prior to 0.42.0 contain a stack overflow vulnerability in the PDF parser due to unbounded recursion when processing deeply nested PDF arrays or dictionaries. A crafted PDF with around 10,000 levels of nested arrays in the Catalog can cause the parser to exhaust the call stack and abort the process with SIGABRT, resulting in a denial of service. This vulnerability does not cause a panic that can be caught, making it effective for crashing services that parse untrusted PDFs. The issue is fixed in lopdf version 0.42.0 by enforcing a maximum object-nesting depth. Join the discussion | GCVE Database | 10/16/2026, 19:55:39 UTC Added: 10/16/2026, 23:10:37 UTC |
