Mozilla Firefox and Thunderbird CRLF Injection Vulnerability

Mozilla Firefox and Thunderbird are prone to a CRLF-injection vulnerability in the 'netwerk/cookie/nsCookieService.cpp' source file.

An attacker can exploit this issue to set multiple cookies in a single call to the 'nsCookieService::SetCookieStringInternal()' function. This may aid in further attacks.
