CVE-2025-43718

Poppler 24.06.1 through 25.x before 25.04.0 allows stack consumption and a SIGSEGV via deeply nested structures within the metadata (such as GTS_PDFEVersion) of a PDF document, e.g., a regular expression for a long pdfsubver string. This occurs in Dict::lookup, Catalog::getMetadata, and associated functions in PDFDoc, with deep recursion in the regex executor (std::__detail::_Executor).

Poppler is 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)
