CVE-2024-47776

Estado: ModificadaMedia (5.1)—

GStreamer is a library for constructing graphs of media-handling components. An OOB-read has been discovered in gst_wavparse_cue_chunk within gstwavparse.c. The vulnerability happens due to a discrepancy between the size of the data buffer and the size value provided to the function. This mismatch causes the comparison if (size < 4 + ncues * 24) to fail in some cases, allowing the subsequent loop to access beyond the bounds of the data buffer. The root cause of this discrepancy stems from a miscalculation when clipping the chunk size based on upstream data size. This vulnerability allows reading beyond the bounds of the data buffer, potentially leading to a crash (denial of service) or the leak of sensitive data. This vulnerability is fixed in 1.24.10.

      "value": "GStreamer es una librería para construir gráficos de componentes de manejo de medios. Se ha descubierto una lectura OOB en gst_wavparse_cue_chunk dentro de gstwavparse.c. La vulnerabilidad ocurre debido a una discrepancia entre el tamaño del búfer de datos y el valor de tamaño proporcionado a la función. Esta falta de coincidencia hace que la comparación if (size &lt; 4 + ncues * 24) falle en algunos casos, lo que permite que el bucle posterior acceda más allá de los límites del búfer de datos. La causa principal de esta discrepancia se origina en un error de cálculo al recortar el tamaño del fragmento en función del tamaño de los datos ascendentes. Esta vulnerabilidad permite leer más allá de los límites del búfer de datos, lo que puede provocar un bloqueo (denegación de servicio) o la fuga de datos confidenciales. Esta vulnerabilidad se corrigió en 1.24.10."
