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.

Security readout for executives and security teams

This is a legacy Mozilla cookie-handling flaw. A malicious website could use a newline in a cookie-setting expression to bypass intended browser access restrictions. Business urgency is mainly tied to whether obsolete Firefox or Thunderbird versions remain in managed desktops, kiosks, VDI images, or archived systems. Exposure is likely limited to environments still running Firefox before 3.6.18, Firefox 4.x through 4.0.1, or Thunderbird before 3.1.11, including legacy Red Hat-packaged builds referenced by advisories. Treat this as a legacy hygiene issue unless vulnerable Mozilla versions are still deployed. It is not KEV-listed in the supplied data, but obsolete browsers can create avoidable exposure and compliance risk. Mitigation focus: Upgrade Firefox to a version newer than the affected ranges.; Upgrade Thunderbird to 3.1.11 or later.; Check Mozilla and Red Hat advisories for vendor-specific package guidance..
