This vulnerability won't be fixed in Fedora 26 and lrzip was removed from later Fedoras. Users are recommended to uninstall this package.

Would you also know something about the state of lrzip in epel? It seems that the last update was in 2016.

You have to ask an EPEL maintainer. See bug #1575073.

Comment 5 Jan Kurik 2018-05-31 08:13:59 UTC

This bug has been reported against a Fedora version which is already unsuported.
In compliance with FESCo decision how to handle EOL of Security issues [1],
I am changing the version to '27', the latest supported release.

Please check whether this bug is still an issue on the '27' release.
If you find this bug not being applicable on this release, please close it.

lrzip does not exist in F27.
