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.
