Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service

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.

libreswan: Malicious IKEv1 Aggressive Mode packets can crash libreswan

pluto in Libreswan before 4.11 allows a denial of service (responder SPI mishandling and daemon crash) via unauthenticated IKEv1 Aggressive Mode packets. The earliest affected version is 3.28.

An issue found in edjing Mix v.7.09.01 for Android allows a local attacker to cause a denial of service via the database files.

Mozilla: User Interface lockup with messages combining S/MIME and OpenPGP

If a MIME email combines OpenPGP and OpenPGP MIME data in a certain way Thunderbird repeatedly attempts to process and display the message, which could cause Thunderbird's user interface to lock up and no longer respond to the user's actions. An attacker could send a crafted message with this structure to attempt a DoS attack. This vulnerability affects Thunderbird < 102.8.

Excessive resource consumption when sending long emoji names in user custom status

Mattermost fails to properly validate the length of the emoji value in the custom user status, allowing an attacker to send multiple times a very long string as an emoji value causing high resource consumption and possibly crashing the server.

Denial of Service via malicious jqPathExpressions in ignoreDifferences

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. There is a Denial of Service (DoS) vulnerability via OOM using jq in ignoreDifferences. This vulnerability has been patched in version(s) 2.10.7, 2.9.12 and 2.8.16.

Argo CD Unauthenticated Denial of Service (DoS) Vulnerability via /api/webhook Endpoint

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. This report details a security vulnerability in Argo CD, where an unauthenticated attacker can send a specially crafted large JSON payload to the /api/webhook endpoint, causing excessive memory allocation that leads to service disruption by triggering an Out Of Memory (OOM) kill. The issue poses a high risk to the availability of Argo CD deployments. This vulnerability is fixed in 2.11.6, 2.10.15, and 2.9.20.

Uncontrolled Resource Consumption vulnerability in ArgoCD's repo server

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All versions of ArgoCD starting from v2.4 have a bug where the ArgoCD repo-server component is vulnerable to a Denial-of-Service attack vector. Specifically, it's possible to crash the repo server component through an out of memory error by pointing it to a malicious Helm registry. The loadRepoIndex() function in the ArgoCD's helm package, does not limit the size nor time while fetching the data. It fetches it and creates a byte slice from the retrieved data in one go. If the registry is implemented to push data continuously, the repo server will keep allocating memory until it runs out of it. A patch for this vulnerability has been released in v2.10.3, v2.9.8, and v2.8.12.

Regular Expression Denial of Service (ReDoS)

All versions of package dat.gui are vulnerable to Regular Expression Denial of Service (ReDoS) via specifically crafted rgb and rgba values.

Panic when parsing invalid messages in google.golang.org/protobuf

Parsing invalid messages can panic. Parsing a text-format message which contains a potential number consisting of a minus sign, one or more characters of whitespace, and no further input will cause a panic.

User input results in Unbounded resource consumption in @zxcvbn-ts/core

zxcvbn-ts is an open source password strength estimator written in typescript. This vulnerability affects users running on the nodeJS platform which are using the second argument of the zxcvbn function. It can result in an unbounded resource consumption as the user inputs array is extended with every function call. Browsers are impacted, too but a single user need to do a lot of input changes so that it affects the browser, while the node process gets the inputs of every user of a platform and can be killed that way. This problem has been patched in version 3.0.2. Users are advised to upgrade. Users unable to upgrade should stop using the second argument of the zxcvbn function and use the zxcvbnOptions.setOptions function.

An issue found in CrossX v.1.15.3 for Android allows a local attacker to cause a persistent denial of service via the database files.

In JetBrains YouTrack before 2023.1.10518 a DoS attack was possible via Helpdesk forms

Directus GraphQL Field Duplication Denial of Service (DoS)

Directus is a real-time API and App dashboard for managing SQL database content. A denial of service (DoS) attack by field duplication in GraphQL is a type of attack where an attacker exploits the flexibility of GraphQL to overwhelm a server by requesting the same field multiple times in a single query. This can cause the server to perform redundant computations and consume excessive resources, leading to a denial of service for legitimate users. Request to the endpoint /graphql are sent when visualizing graphs generated at a dashboard. By modifying the data sent and duplicating many times the fields a DoS attack is possible. This vulnerability is fixed in 10.12.0.

jtidy: denial of service via crafted object that uses cyclic dependencies

An issue was discovered jtidy thru r938 allows attackers to cause a denial of service or other unspecified impacts via crafted object that uses cyclic dependencies.

Werkzeug possible resource exhaustion when parsing file data in forms

Werkzeug is a Web Server Gateway Interface web application library. Applications using `werkzeug.formparser.MultiPartParser` corresponding to a version of Werkzeug prior to 3.0.6 to parse `multipart/form-data` requests (e.g. all flask applications) are vulnerable to a relatively simple but effective resource exhaustion (denial of service) attack. A specifically crafted form submission request can cause the parser to allocate and block 3 to 8 times the upload size in main memory. There is no upper limit; a single upload at 1 Gbit/s can exhaust 32 GB of RAM in less than 60 seconds. Werkzeug version 3.0.6 fixes this issue.
