| CVE-2020-15166 | 3 Debian, Fedoraproject, Zeromq | 3 Debian Linux, Fedora, Libzmq | 2023-11-07 | 7.5 High |
| In ZeroMQ before version 4.3.3, there is a denial-of-service vulnerability. Users with TCP transport public endpoints, even with CURVE/ZAP enabled, are impacted. If a raw TCP socket is opened and connected to an endpoint that is fully configured with CURVE/ZAP, legitimate clients will not be able to exchange any message. Handshakes complete successfully, and messages are delivered to the library, but the server application never receives them. This is patched in version 4.3.3. | ||||
| CVE-2020-15114 | 2 Fedoraproject, Redhat | 2 Fedora, Etcd | 2023-11-07 | 7.7 High |
| In etcd before versions 3.3.23 and 3.4.10, the etcd gateway is a simple TCP proxy to allow for basic service discovery and access. However, it is possible to include the gateway address as an endpoint. This results in a denial of service, since the endpoint can become stuck in a loop of requesting itself until there are no more available file descriptors to accept connections on the gateway. | ||||
| CVE-2020-13949 | 2 Apache, Oracle | 4 Hive, Thrift, Communications Cloud Native Core Network Slice Selection Function and 1 more | 2023-11-07 | 7.5 High |
| In Apache Thrift 0.9.3 to 0.13.0, malicious RPC clients could send short messages which would result in a large memory allocation, potentially leading to denial of service. | ||||
| CVE-2020-12662 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-11-07 | 7.5 High |
| Unbound before 1.10.1 has Insufficient Control of Network Message Volume, aka an "NXNSAttack" issue. This is triggered by random subdomains in the NSDNAME in NS records. | ||||
| CVE-2020-11080 | 6 Debian, Fedoraproject, Nghttp2 and 3 more | 10 Debian Linux, Fedora, Nghttp2 and 7 more | 2023-11-07 | 7.5 High |
| In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection. | ||||
| CVE-2020-10995 | 4 Debian, Fedoraproject, Opensuse and 1 more | 5 Debian Linux, Fedora, Backports Sle and 2 more | 2023-11-07 | 7.5 High |
| PowerDNS Recursor from 4.1.0 up to and including 4.3.0 does not sufficiently defend against amplification attacks. An issue in the DNS protocol has been found that allow malicious parties to use recursive DNS services to attack third party authoritative name servers. The attack uses a crafted reply by an authoritative name server to amplify the resulting traffic between the recursive and other authoritative name servers. Both types of service can suffer degraded performance as an effect. This is triggered by random subdomains in the NSDNAME in NS records. PowerDNS Recursor 4.1.16, 4.2.2 and 4.3.1 contain a mitigation to limit the impact of this DNS protocol issue. | ||||
| CVE-2020-10772 | 2 Nlnetlabs, Redhat | 2 Unbound, Enterprise Linux | 2023-11-07 | 7.5 High |
| An incomplete fix for CVE-2020-12662 was shipped for Unbound in Red Hat Enterprise Linux 7, as part of erratum RHSA-2020:2414. Vulnerable versions of Unbound could still amplify an incoming query into a large number of queries directed to a target, even with a lower amplification ratio compared to versions of Unbound that shipped before the mentioned erratum. This issue is about the incomplete fix for CVE-2020-12662, and it does not affect upstream versions of Unbound. | ||||
| CVE-2020-10745 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Leap and 1 more | 2023-11-07 | 7.5 High |
| A flaw was found in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4 in the way it processed NetBios over TCP/IP. This flaw allows a remote attacker could to cause the Samba server to consume excessive CPU use, resulting in a denial of service. This highest threat from this vulnerability is to system availability. | ||||
| CVE-2019-9518 | 11 Apache, Apple, Canonical and 8 more | 20 Traffic Server, Mac Os X, Swiftnio and 17 more | 2023-11-07 | 7.5 High |
| 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 bandwidth. This can consume excess CPU. | ||||
| CVE-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 25 Http Server, Traffic Server, Mac Os X and 22 more | 2023-11-07 | 7.5 High |
| 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 requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. | ||||
| CVE-2019-9516 | 12 Apache, Apple, Canonical and 9 more | 21 Traffic Server, Mac Os X, Swiftnio and 18 more | 2023-11-07 | 6.5 Medium |
| 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 session dies. This can consume excess memory. | ||||
| CVE-2019-9515 | 12 Apache, Apple, Canonical and 9 more | 24 Traffic Server, Mac Os X, Swiftnio and 21 more | 2023-11-07 | 7.5 High |
| 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 this data is queued, this can consume excess CPU, memory, or both. | ||||
| CVE-2019-9514 | 13 Apache, Apple, Canonical and 10 more | 30 Traffic Server, Mac Os X, Swiftnio and 27 more | 2023-11-07 | 7.5 High |
| 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-2019-9513 | 12 Apache, Apple, Canonical and 9 more | 22 Traffic Server, Mac Os X, Swiftnio and 19 more | 2023-11-07 | 7.5 High |
| 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-2019-9512 | 5 Apache, Apple, Canonical and 2 more | 6 Traffic Server, Mac Os X, Swiftnio and 3 more | 2023-11-07 | 7.5 High |
| 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 this data is queued, this can consume excess CPU, memory, or both. | ||||
| CVE-2019-9511 | 12 Apache, Apple, Canonical and 9 more | 22 Traffic Server, Mac Os X, Swiftnio and 19 more | 2023-11-07 | 7.5 High |
| 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. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | ||||
| CVE-2019-6477 | 2 Fedoraproject, Isc | 2 Fedora, Bind | 2023-11-07 | 7.5 High |
| With pipelining enabled each incoming query on a TCP connection requires a similar resource allocation to a query received via UDP or via TCP without pipelining enabled. A client using a TCP-pipelined connection to a server could consume more resources than the server has been provisioned to handle. When a TCP connection with a large number of pipelined queries is closed, the load on the server releasing these multiple resources can cause it to become unresponsive, even for queries that can be answered authoritatively or from cache. (This is most likely to be perceived as an intermittent server problem). | ||||
| CVE-2019-5419 | 5 Debian, Fedoraproject, Opensuse and 2 more | 6 Debian Linux, Fedora, Leap and 3 more | 2023-11-07 | 7.5 High |
| There is a possible denial of service vulnerability in Action View (Rails) <5.2.2.1, <5.1.6.2, <5.0.7.2, <4.2.11.1 where specially crafted accept headers can cause action view to consume 100% cpu and make the server unresponsive. | ||||
| CVE-2019-25072 | 1 Tendermint | 1 Tendermint | 2023-11-07 | 7.5 High |
| Due to support of Gzip compression in request bodies, as well as a lack of limiting response body sizes, a malicious server can cause a client to consume a significant amount of system resources, which may be used as a denial of service vector. | ||||
| CVE-2019-20446 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2023-11-07 | 6.5 Medium |
| In xml.rs in GNOME librsvg before 2.46.2, a crafted SVG file with nested patterns can cause denial of service when passed to the library for processing. The attacker constructs pattern elements so that the number of final rendered objects grows exponentially. | ||||
