HTTP/2: request for large response leads to denial of service
A vulnerability was found in HTTP/2. An attacker can open a HTTP/2 window so the peer can send without constraint. The TCP window remains closed so the peer cannot write the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the server's...
HTTP/2: flood using SETTINGS frames results in unbounded memory growth
A flaw was found in HTTP/2. Using SETTINGS frames and queuing of SETTINGS ACK frames, a flood could occur resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability...
The vulnerability of IPv6 network protocol implementations in the Linux operating system allows a perpetrator to gain unauthorized access to protected information.
The vulnerability of IPv6 network protocol implementations in the Linux operating system’s kernel is related to the lack of protection for data transmitted through the IPsec tunnel. Exploiting this vulnerability can allow a malicious actor, operating remotely, to gain unauthorized access to...
