CVE-2009-2855 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-2855):
  The strListGetItem function in src/HttpHeaderTools.c in Squid 2.7
  allows remote attackers to cause a denial of service via a crafted
  auth header with certain comma delimiters that trigger an infinite
  loop of calls to the strcspn function.
