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."}, {"lang": "es", "value": "DjVuLibre es una implementaci\u00f3n GPL de DjVu, un formato web para distribuir documentos e im\u00e1genes.
