=perl-core/Compress-Raw-Bzip2-2.020 is stable, so this is glsa-ready.

CVE-2009-1884 (
  Off-by-one error in the bzinflate function in Bzip2.xs in the
  Compress-Raw-Bzip2 module before 2.018 for Perl allows
  context-dependent attackers to cause a denial of service (application
  hang or crash) via a crafted bzip2 compressed stream that triggers a
  buffer overflow, a related issue to CVE-2009-1391.
