The vulnerability is in libjpeg, a transitive dependency of fiona (via GDAL and PROJ).\n\n### Details\nIn IJG JPEG (aka libjpeg) before 9d, jpeg_mem_available() in jmemnobs.c in djpeg does not honor the max_memory_to_use setting, possibly causing excessive memory consumption.\n\n### Impact\nfiona will not open JPEG files and is not vulnerable to attack in that way. fiona might be vulnerable to malformed PROJ grid files using JPEG compression. No such vulnerability or compromise has been demonstrated.\n",
