CVE-2025-52886 | BDVDB-2026-284530 Detail
popplerpoppler
Description#
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.
Impact#
Per CVSS v4.0: confidentiality impact none, integrity impact none, availability impact high. Attack vector: local.
Weaknesses#
- CWE-416 Use After Free
