Source: poppler Version: 25.03.0-4 Severity: important Tags: security upstream Forwarded: https://gitlab.freedesktop.org/poppler/poppler/-/issues/1581 X-Debbugs-Cc: car...@debian.org, Debian Security Team <t...@security.debian.org>
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.
