      "value": "GStreamer is a library for constructing graphs of media-handling components. An uninitialized stack variable vulnerability has been identified in the gst_matroska_demux_add_wvpk_header function within matroska-demux.c. When size < 4, the program calls gst_buffer_unmap with an uninitialized map variable. Then, in the gst_memory_unmap function, the program will attempt to unmap the buffer using the uninitialized map variable, causing a function pointer hijack, as it will jump to mem->allocator->mem_unmap_full or mem->allocator->mem_unmap. This vulnerability could allow an attacker to hijack the execution flow, potentially leading to code execution. This vulnerability is fixed in 1.24.10."

Se ha identificado una vulnerabilidad de variable de pila no inicializada en la funci\u00f3n gst_matroska_demux_add_wvpk_header dentro de matroska-demux.c. Cuando size &lt; 4, el programa llama a gst_buffer_unmap con una variable de mapa no inicializada. Luego, en la funci\u00f3n gst_memory_unmap, el programa intentar\u00e1 desasignar el b\u00fafer utilizando la variable de mapa no inicializada, lo que provocar\u00e1 un secuestro del puntero de funci\u00f3n, ya que saltar\u00e1 a mem-&gt;allocator-&gt;mem_unmap_full o mem-&gt;allocator-&gt;mem_unmap. Esta vulnerabilidad podr\u00eda permitir que un atacante secuestre el flujo de ejecuci\u00f3n, lo que podr\u00eda provocar la ejecuci\u00f3n del c\u00f3digo.
