            Bug ID: 11531
           Summary: tar: archive with first member named BZh[1-9] is not
                    handled correctly
           Product: Busybox
           Version: 1.33.x
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at busybox.net
          Reporter: mgorny at gentoo.org
                CC: busybox-cvs at busybox.net
  Target Milestone: ---

If the first .tar member is named BZh[1-9], the archive is incorrectly
recognized as bzip2-compressed:

$ busybox tar -xf ustar.tar 
tar: bunzip error -2
tar: short read

While such a filename is not very likely, it's a technically valid tarball.

To reproduce:
$ echo test > BZh5
$ tar -cf ustar.tar BZh5
