Title
GHSL-2025-042: Poppler has Use-After-Free
Summary
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.

"value": "Poppler es una biblioteca para renderizar archivos PDF, y examinar o modificar su estructura. Se ha detectado una vulnerabilidad de uso despu\u00e9s de liberaci\u00f3n (escritura) en versiones de Poppler anteriores a la 25.10.0 dentro de la clase StructTreeRoot. El problema surge del uso de punteros crudos a elementos de un \u0027std::vector\u0027, lo que puede llevar a punteros colgantes cuando el vector se redimensiona. La vulnerabilidad se origina en la forma en que refToParentMap almacena referencias a elementos de \u0027std::vector\u0027 utilizando punteros crudos. Estos punteros pueden volverse inv\u00e1lidos cuando el vector se redimensiona. Esta vulnerabilidad es un problema de seguridad com\u00fan que implica el uso de punteros crudos a \u0027std::vectors\u0027. Internamente, \u0027std::vector\u0027 almacena sus elementos en un array asignado din\u00e1micamente. Cuando el array alcanza su capacidad y se a\u00f1ade un nuevo elemento, el vector reasigna un bloque de memoria m\u00e1s grande y mueve todos los elementos existentes a la nueva ubicaci\u00f3n. En este punto, si se almacenan punteros a elementos antes de que ocurra un redimensionamiento, se convierten en punteros colgantes una vez que ocurre la reasignaci\u00f3n. La versi\u00f3n 25.10.0 contiene un parche para el problema."
