Fedora 29: FEDORA-2018-2b7e72dc9f Moderate: Zchunk Integrity Enhancements

zchunk is a compressed file format that splits the file into independent

chunks. This allows you to only download the differences when downloading a

new version of the file, and also makes zchunk files efficient over rsync.

zchunk files are protected with strong checksums to verify that the file you

downloaded is in fact the file you wanted.

This update does sanity checking when an application passes in a checksum to

verify. Before this release, applications could pass in non-hex values for the

checksum, which could cause zchunk to crash. Now non-hex values will be

rejected.
