gir1.2-poppler-0.18: Poppler ia a library for rendering PDF files, and examining or modifyingtheir structure

Poppler ia a library for rendering PDF files, and examining or modifyingtheir structure. A use-after-free (write) vulnerability has been detectedin versions Poppler prior to 25.10.0 within the StructTreeRoot class. Theissue arises from the use of raw pointers to elements of a `std::vector`,which can lead to dangling pointers when the vector is resized. Thevulnerability stems from the way that refToParentMap stores references to`std::vector` elements using raw pointers. These pointers may becomeinvalid when the vector is resized. This vulnerability is a common securityproblem involving the use of raw pointers to `std::vectors`. Internally,`std::vector `stores its elements in a dynamically allocated array. Whenthe array reaches its capacity and a new element is added, the vectorreallocates a larger block of memory and moves all the existing elements tothe new location. At this point if any pointers to elements are storedbefore a resize occurs, they become dangling pointers once the reallocationhappens. Version 25.10.0 contains a patch for the issue.
