 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.
