  It was discovered that logrotate incorrectly handled certain log file
  names when used with the shred option. Local attackers able to create log
  files with specially crafted filenames could use this issue to execute
  arbitrary code. This issue only affected Ubuntu 10.04 LTS, 10.10, and

  It was discovered that logrotate incorrectly handled certain malformed log
  filenames. Local attackers able to create log files with specially crafted
  filenames could use this issue to cause logrotate to stop processing log
  files, resulting in a denial of service. (CVE-2011-1155)
  
  It was discovered that logrotate incorrectly handled symlinks and hard
  links when processing log files. A local attacker having write access to
  a log file directory could use this issue to overwrite or read arbitrary
  files. This issue only affected Ubuntu 8.04 LTS. (CVE-2011-1548)";
