"The version of Poppler installed on the remote host is prior to 25.10.0. It is, therefore, affected by a vulnerability:

  - 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. (CVE-2025-52885)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
