Hi,

The following vulnerability was published for poppler.

CVE-2025-52886[0]:
| 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.

Unfortunately it looks that the report came in while there was already
some rejactoring in the refcounting, cf. [2] so this might come more
intrusive.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
