CVE-2019-12854 [HIGH] CVE-2019-12854: Due to incorrect string termination, Squid cachemgr.cgi 4.0 through 4.7 may access unallocated memor Due to incorrect string termination, Squid cachemgr.cgi 4.0 through 4.7 may access unallocated memory. On systems with memory access protections, this can cause the CGI process to terminate unexpectedly, resulting in a denial of service for all clients using it.

CVE-2019-13377 [MEDIUM] CWE-203 CVE-2019-13377: The implementations of SAE and EAP-pwd in hostapd and wpa_supplicant 2.x through 2.8 are vulnerable The implementations of SAE and EAP-pwd in hostapd and wpa_supplicant 2.x through 2.8 are vulnerable to side-channel attacks as a result of observable timing differences and cache access patterns when Brainpool curves are used. An attacker may be able to gain leaked information from a side-channel attack that can be used for full password recovery.

CVE-2019-9506 [HIGH] CWE-310 CVE-2019-9506: The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encrypti The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.

CVE-2019-9515 [HIGH] CWE-400 CVE-2019-9515: Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of s Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently th

CVE-2017-18509 [HIGH] CWE-20 CVE-2017-18509: An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific s An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC c

CVE-2019-9517 [HIGH] CWE-400 CVE-2019-9517: Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially lead Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requ

CVE-2019-9514 [HIGH] CWE-400 CVE-2019-9514: Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of serv Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both

CVE-2019-9511 [HIGH] CWE-400 CVE-2019-9511: Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization man Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. De

CVE-2019-9513 [HIGH] CWE-400 CVE-2019-9513: Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of ser Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU.

CVE-2019-9518 [HIGH] CWE-400 CVE-2019-9518: Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a deni Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandw

CVE-2019-9516 [MEDIUM] CWE-400 CVE-2019-9516: Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of serv Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the
