Hi, The following vulnerability was published for poppler. CVE-2025-52885[0]: | Poppler ia a library for rendering PDF files, and examining or | modifying their structure. A use-after-free (write) vulnerability | has been detected in versions Poppler prior to 25.10.0 within the | StructTreeRoot class. The issue arises from the use of raw pointers | to elements of a `std::vector`, which can lead to dangling pointers | when the vector is resized. The vulnerability stems from the way | that refToParentMap stores references to `std::vector` elements | using raw pointers. These pointers may become invalid when the | vector is resized. This vulnerability is a common security problem | involving the use of raw pointers to `std::vectors`. Internally, | `std::vector `stores its elements in a dynamically allocated array. | When the array reaches its capacity and a new element is added, the | vector reallocates a larger block of memory and moves all the | existing elements to the new location. At this point if any pointers | to elements are stored before a resize occurs, they become dangling | pointers once the reallocation happens. Version 25.10.0 contains a | patch for the issue. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
