Description Mario Kicherer 2012-12-17 10:25:40 UTC

Version 0.8.8 came out 2012/12/06. I tested it with the fail2ban-0.8.7.1 ebuild and it works for me on AMD64.

Reproducible: Always

   * [83109bc] IMPORTANT: escape the content of <matches> (if used in
     custom action files) since its value could contain arbitrary
     symbols.  Thanks for discovery go to the NBS System security
     team

CVE-2012-5642 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5642):
  server/action.py in Fail2ban before 0.8.8 does not properly handle the
  content of the matches tag, which might allow remote attackers to trigger
  unsafe behavior in a custom action file via unspecified symbols in this
  content.
