Tntnet, a web application server for web applications, was found to be affected by a vulnerability, where by sending a crafted HTTP request that uses "\n" to end its headers instead of the expected "\r\n", it is possible that headers from a previous unrelated request will seemingly be appended to the crafted request (due to a missing null termination). This allows a remote attacker to use sensitive headers from other users' requests in their own requests, such as cookies or HTTP authentication credentials. The issue is said to be fixed in tntnet 2.2.1.
