| description: | |
| Due to a goroutine deadlock, using github.com/containers/storage/pkg/archive.DecompressStream |
| on a xz archive returns a reader which will hang indefinitely when Close is called. An attacker |
| can use this to cause denial of service if they are able to cause the caller to attempt to |
| decompress an archive they control. |
