tag_insight = "The gzip package provides the GNU gzip data compression program.

  An integer underflow flaw, leading to an array index error, was found in
  the way gzip expanded archive files compressed with the Lempel-Ziv-Welch
  (LZW) compression algorithm. If a victim expanded a specially-crafted
  archive, it could cause gzip to crash or, potentially, execute arbitrary
  code with the privileges of the user running gzip. This flaw only affects
  64-bit systems. (CVE-2010-0001)
  
  Red Hat would like to thank Aki Helin of the Oulu University Secure
  Programming Group for responsibly reporting this flaw.
  
  Users of gzip should upgrade to this updated package, which contains a
  backported patch to correct this issue.";
