HTTP/2: flood using PRIORITY frames results in excessive resource consumption

A flaw was found in HTTP/2. An attacker, using PRIORITY frames to flood the system, could cause excessive CPU usage and starvation of other clients. The largest threat from this vulnerability is to system availability...

Denial Of Service (DoS)

nginx HTTP/2 is vulnerable to denial of service DoS. It does not prevent the attacker from creating multiple request streams and flooding using PRIORITY frames continuously in a way that causes substantial churn to the priority tree, causing an excessive resource consumption...

UBUNTU-CVE-2019-16275

hostapd before 2.10 and wpasupplicant before 2.10 allow an incorrect indication of disconnection in certain situations because source address validation is mishandled. This is a denial of service that should have been prevented by PMF aka management frame protection. The attacker must send a...

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...

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

A flaw was found in HTTP/2. Using PING frames and queuing of response PING ACK frames, a flood attack could occur resulting in unbounded memory growth. The highest threat from this vulnerability is to system availability...

kernel: brcmfmac frame validation bypass

If the brcmfmac driver receives a firmware event frame from a remote source, the iswlceventframe function will cause this frame to be discarded and not be processed. If the driver receives the firmware event frame from the host, the appropriate handler is called. This frame validation can be...

MGASA-2019-0251 Updated golang packages fix security vulnerabilities

Updated golang packages fix security vulnerabilities: Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently...

Denial Of Service (DoS)

github.com/gorilla/websocket is vulnerable to denial of service DoS. An integer overflow in conn.go when parsing WebSocket frames allows a remote attacker to cause the server to consume excessive amount of memory, resulting in an application crash when the server runs out of memory...

kernel: brcmfmac heap buffer overflow in brcmf_wowl_nd_results

If the Wake-up on Wireless LAN functionality is configured in the brcmfmac driver, which only works with Broadcom FullMAC chipsets, a malicious event frame can be constructed to trigger a heap buffer overflow in the brcmfwowlndresults function. This vulnerability can be exploited by compromised...
