Description Agostino Sarubbo gentoo-dev 2012-11-15 18:36:12 UTC
From https://bugzilla.redhat.com/show_bug.cgi?id=877015 :

A security flaw was found in the way CGI.pm, a Perl module to handle Common Gateway Interface 
requests and responses, performed sanitization of values to be used for Set-Cookie and P3P headers. 
If a Perl CGI.pm module based CGI application reused cookies values and accepted untrusted input 
from web browser(s), a remote attacker could use this flaw to in an unauthorized way alter member 
items of the cookie or add new items.

CVE-2012-5526 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5526):
  CGI.pm module before 3.63 for Perl does not properly escape newlines in (1)
  Set-Cookie or (2) P3P headers, which might allow remote attackers to inject
  arbitrary headers into responses from applications that use CGI.pm.
