Description Doran Moppert 2016-06-23 00:16:40 UTC
A denial of service was discovered in libarchive in the processing of .iso
files.  A specially crafted .iso could cause the process to go into an (almost)
endless loop, eventually exiting with an error after hitting memory limits.

libarchive-2.8 does not support the required construct in ISO files.
