CVE-2025-52886 Details
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.
A use-after-free vulnerability has been identified in Poppler, a PDF rendering library, in versions prior to 25.06.0. The issue arises because the library uses 'std::atomic_int' for reference counting, which is limited to 32 bits. This limitation allows for an integer overflow in the reference count, leading to a use-after-free condition. The vulnerability can be exploited by crafting a PDF file that creates a large number of annotations, causing the reference count to overflow and free an object that is still in use.
Users can upgrade to Poppler version 25.06.0 or later, where this vulnerability has been fixed.
