Working with specific payloads can cause a Denial of Service (DoS) vector.
Compress implementations can enter into infinite loops
given specific payloads entered that trigger it.
The issue is described in great detail in the bzip2 repository issue.
Thanks to bjrjk for finding and providing the patch for the issue and the maintainer responsibly responding to release a fix quickly.
Users who use the crate with untrusted data should update the
bzip2 to 0.4.4.
