Fedora 37: FEDORA-2023-5a4fd08de9 Low Severity Zchunk Issue

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.

Fix several low severity security bugs.

* Tue Apr 4 2023 Jonathan Dieter - 1.3.1-1

- Fix a few low severity security bugs including

- An off-by-one overflow when reading compressed integers from a

malicious zchunk file

- Error handling being skipped when the number of bytes read doesn't

match what's expected

- Not freeing memory when attempting to reallocate to size 0
