CVE-2025-52886
MEDIUMpoppler < 25.06.0 - Use-After-Free via Reference Count Overflow
Title source: llmDescription
Poppler is a PDF rendering library. Versions prior to 25.06.0 use `std::atomic_int` for reference counting. Because `std::atomic_int` is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue.
