## Description

CRLF injection vulnerability in the
nsCookieService::SetCookieStringInternal function in
netwerk/cookie/nsCookieService.cpp in Mozilla Firefox before 3.6.18 and 4.x
through 4.0.1, and Thunderbird before 3.1.11, allows remote attackers to
bypass intended access restrictions via a string containing a \n (newline)
character, which is not properly handled in a JavaScript "document.cookie
=" expression, a different vulnerability than CVE-2011-2374.
