nodejs: CONTINUATION frames DoS

An attacker can make the Node.js HTTP/2 server completely unavailable by sending a small amount of HTTP/2 frames packets with a few HTTP/2 frames inside. It is possible to leave some data in nghttp2 memory after reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is abruptly closed by the client triggering the Http2Session destructor while header frames are still being processed (and stored in memory) causing a race condition.

Bematech Printer MP-4200 TH Denial of Service

Bematech (formerly Logic Controls, now Elgin) MP-4200 TH printer contains a denial of service vulnerability in the admin configuration page. Remote attackers can send crafted POST requests with malformed 'admin' and 'person' parameters to crash the printer's web service, causing a denial of service condition.

nodejs: GOAWAY HTTP/2 frames cause memory leak outside heap

A memory leak could occur when a remote peer abruptly closes the socket without sending a GOAWAY notification. Additionally, if an invalid header was detected by nghttp2, causing the connection to be terminated by the peer, the same leak was triggered. This flaw could lead to increased memory consumption and potential denial of service under certain conditions. This vulnerability affects HTTP/2 Server users on Node.js v18.x, v20.x, v22.x and v23.x.

Cisco BroadWorks Network Server TCP Denial of Service Vulnerability

A vulnerability in the local interface of Cisco BroadWorks Network Server could allow an unauthenticated, remote attacker to exhaust system resources, causing a denial of service (DoS) condition. This vulnerability exists because rate limiting does not occur for certain incoming TCP connections. An attacker could exploit this vulnerability by sending a high rate of TCP connections to the server. A successful exploit could allow the attacker to cause TCP connection resources to grow rapidly until the Cisco BroadWorks Network Server becomes unusable. Note: To recover from this vulnerability, either Cisco BroadWorks Network Server software must be restarted or the Cisco BroadWorks Network Server node must be rebooted. For more information, see the section of this advisory. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

intel-microcode: Unexpected behavior in Intel(R) Core(TM) Ultra Processors

Sequence of processor instructions leads to unexpected behavior in Intel(R) Core(TM) Ultra Processors may allow an authenticated user to potentially enable denial of service via local access.

erlang-jose: Denial-of-service due to high CPU consumption

erlang-jose (aka JOSE for Erlang and Elixir) through 1.11.6 allow attackers to cause a denial of service (CPU consumption) via a large p2c (aka PBES2 Count) value in a JOSE header.

An issue in obgm and Libcoap v.a3ed466 allows a remote attacker to cause a denial of service via thecoap_context_t function in the src/coap_threadsafe.c:297:3 component.

A flood of DNS messages over TCP may make the server unstable

A malicious client can send many DNS messages over TCP, potentially causing the server to become unstable while the attack is in progress. The server may recover after the attack ceases. Use of ACLs will not mitigate the attack. This issue affects BIND 9 versions 9.18.1 through 9.18.27, 9.19.0 through 9.19.24, and 9.18.11-S1 through 9.18.27-S1.

Many records in the additional section cause CPU exhaustion

It is possible to construct a zone such that some queries to it will generate responses containing numerous records in the Additional section. An attacker sending many such queries can cause either the authoritative server itself or an independent resolver to use disproportionate resources processing the queries. Zones will usually need to have been deliberately crafted to attack this exposure. This issue affects BIND 9 versions 9.11.0 through 9.11.37, 9.16.0 through 9.16.50, 9.18.0 through 9.18.32, 9.20.0 through 9.20.4, 9.21.0 through 9.21.3, 9.11.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.50-S1, and 9.18.11-S1 through 9.18.32-S1.

IKEv2 misconfiguration can cause libreswan to abort and restart

The Libreswan Project was notified of an issue causing libreswan to restart under some IKEv2 retransmit scenarios when a connection is configured to use PreSharedKeys (authby=secret) and the connection cannot find a matching configured secret. When such a connection is automatically added on startup using the auto= keyword, it can cause repeated crashes leading to a Denial of Service.

A reachable assertion in the decode_access_point_name_ie function of Magma <= 1.8.0 (fixed in v1.9 commit 08472ba98b8321f802e95f5622fa90fec2dea486) allows attackers to cause a Denial of Service (DoS) via a crafted NAS packet.

OpenID Connect client Atom Exhaustion in provider configuration worker ets table location

oidcc is the OpenID Connect client library for Erlang. Denial of Service (DoS) by Atom exhaustion is possible by calling `oidcc_provider_configuration_worker:get_provider_configuration/1` or `oidcc_provider_configuration_worker:get_jwks/1`. This issue has been patched in version(s)`3.1.2` & `3.2.0-beta.3`.

go-ethereum denial of service via malicious p2p message

go-ethereum (geth) is a golang execution layer implementation of the Ethereum protocol. Prior to 1.13.15, a vulnerable node can be made to consume very large amounts of memory when handling specially crafted p2p messages sent from an attacker node. The fix has been included in geth version `1.13.15` and onwards.

Yamux Memory Exhaustion Vulnerability via Active::pending_frames property

Yamux is a stream multiplexer over reliable, ordered connections such as TCP/IP. The Rust implementation of the Yamux stream multiplexer uses a vector for pending frames. This vector is not bounded in length. Every time the Yamux protocol requires sending of a new frame, this frame gets appended to this vector. This can be remotely triggered in a number of ways, for example by: 1. Opening a new libp2p Identify stream. This causes the node to send its Identify message. Of course, every other protocol that causes the sending of data also works. The larger the response, the more data is enqueued. 2. Sending a Yamux Ping frame. This causes a Pong frame to be enqueued. Under normal circumstances, this queue of pending frames would be drained once they’re sent out over the network. However, the attacker can use TCP’s receive window mechanism to prevent the victim from sending out any data: By not reading from the TCP connection, the receive window will never be increased, and the victim won’t be able to send out any new data (this is how TCP implements backpressure). Once this happens, Yamux’s queue of pending frames will start growing indefinitely. The queue will only be drained once the underlying TCP connection is closed. An attacker can cause a remote node to run out of memory, which will result in the corresponding process getting terminated by the operating system.

An issue was discovered in O-RAN Near Realtime RIC H-Release. To trigger the crashing of the e2mgr, an adversary must flood the system with a significant quantity of E2 Subscription Requests originating from an xApp.

An issue was discovered in O-RAN Near Realtime RIC I-Release. To exploit this vulnerability, an attacker can disrupt the initial connection between a gNB and the Near RT-RIC by inundating the system with a high volume of subscription requests via an xApp.

octo-sts allows unauthenticated attackers to cause unbounded CPU and memory usage

octo-sts is a GitHub App that acts like a Security Token Service (STS) for the Github API. This vulnerability can spike the resource utilization of the STS service, and combined with a significant traffic volume could potentially lead to a denial of service. This vulnerability is fixed in 0.1.0

Minder's Github Webhook Handler vulnerable to denial of service from un-validated requests

Minder's `HandleGithubWebhook` is susceptible to a denial of service attack from an untrusted HTTP request. The vulnerability exists before the request has been validated, and as such the request is still untrusted at the point of failure. This allows an attacker with the ability to send requests to `HandleGithubWebhook` to crash the Minder controlplane and deny other users from using it. This vulnerability is fixed in 0.0.48.

An issue in XINJE XL5E-16T V3.7.2a allows attackers to cause a Denial of Service (DoS) via a crafted Modbus message.
