Mozilla Firefox, Thunderbird, and SeaMonkey Location Header HTTP Response Splitting Vulnerability

2015 January 29 14:20 GMT
Mozilla Firefox, Thunderbird, and SeaMonkey contain a vulnerability that could allow an unauthenticated, remote attacker to conduct HTTP response splitting attacks against a targeted system.
The vulnerability is due to insufficient sanitization of user-supplied input while processing two copies of the HTTP request headers.
An unauthenticated, remote attacker could exploit the vulnerability by transmitting HTTP requests crafted with arbitrary location headers. When processed, the requests could allow the attacker to redirect the user to a different website.
Mozilla has mitigated the vulnerability by generating an error condition if two copies of the header with different values are detected.
Mozilla has confirmed the vulnerability and released software updates.
Administrators are advised to apply the appropriate updates.
Users are advised not to visit websites or follow links that have suspicious characteristics or cannot be verified as safe.
Administrators are advised to apply Snort SID 20583 to help prevent attacks that attempt to exploit the vulnerability.
Administrators are advised to monitor affected systems.
