      "value": "DjVuLibre is a GPL implementation of DjVu, a web-centric format for distributing documents and images. Prior to version 3.5.29, the MMRDecoder::scanruns method is affected by an OOB-write vulnerability, because it does not check that the xr pointer stays within the bounds of the allocated buffer. This can lead to writes beyond the allocated memory, resulting in a heap corruption condition. An out-of-bounds read with pr is also possible for the same reason. This issue has been patched in version 3.5.29."

Antes de la versión 3.5.29, el método MMRDecoder::scanruns presentaba una vulnerabilidad de escritura fuera de banda (OOB), ya que no comprobaba que el puntero xr se mantuviera dentro de los límites del búfer asignado. Esto podía provocar escrituras fuera de la memoria asignada, lo que resultaba en una condición de corrupción del montón. Una lectura fuera de los límites con pr también era posible por la misma razón. Este problema se ha corregido en la versión 3.5.29."
