HTTP/2: 0-length headers lead to denial of service

A flaw was found in HTTP/2. An attacker, sending a stream of header with a 0-length header name and a 0-length header value, could cause some implementations to allocate memory for these headers and keep the allocations alive until the session dies. The can consume excess memory, potentially...

HTTP/2: flood using HEADERS frames results in unbounded memory growth

A flaw was found in HTTP/2. Using HEADER frames with invalid HTTP headers and queuing of response RSTSTREAM frames, an attacker could cause a flood resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability...

hardware: bluetooth: BR/EDR encryption key negotiation attacks (KNOB)

A flaw was discovered in the Bluetooth protocol. An attacker within physical proximity to the Bluetooth connection could downgrade the encryption protocol to be trivially brute forced...

HTTP/2: large amount of data requests leads to denial of service

A flaw was found in HTTP/2. An attacker can request a large amount of data by manipulating window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this queue can consume excess CPU, memory, or both, leading to a...
