Passport-SAML is a SAML 2.0 authentication provider for Passport, the Node.js authentication library. Prior to version 3.1.0, a malicious SAML payload can require transforms that consume significant system resources to process, thereby resulting in reduced or denied service. This would be an effective way to perform a denial-of-service attack. This has been resolved in version 3.1.0. The resolution is to limit the number of allowable transforms to 2.

This can potentially reduce the availability of a Discourse instance. This problem has been patched in the latest version of Discourse. All users area are advised to upgrade. There are no known workarounds for this vulnerability.
Internet Small Computer Systems Interface (iSCSI) Denial of Service Vulnerability
fugit contains time tools for flor and the floraison group. The fugit "natural" parser, that turns "every wednesday at 5pm" into "0 17 * * 3", accepted any length of input and went on attempting to parse it, not returning promptly, as expected. The parse call could hold the thread with no end in sight. Fugit dependents that do not check (user) input length for plausibility are impacted. A fix was released in fugit 1.11.1.
Tenda FH1206 v02.03.01.35 was discovered to contain a stack overflow via the page parameter in the frmL7ImForm function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted POST request.

Apprise is an open source library which allows you to send a notification to almost all of the most popular notification services available. In affected versions users who use Apprise granting them access to the IFTTT plugin (which just comes out of the box) are subject to a denial of service attack on an inefficient regular expression. The vulnerable regular expression is [here](https://github.com/caronc/apprise/blob/0007eade20934ddef0aba38b8f1aad980cfff253/apprise/plugins/NotifyIFTTT.py#L356-L359). The problem has been patched in release version 0.9.5.1. Users who are unable to upgrade are advised to remove `apprise/plugins/NotifyIFTTT.py` to eliminate the service.
Skyport Daemon (skyportd) is the daemon for the Skyport Panel. By making thousands of folders & files (easy due to skyport's lack of rate limiting on createFolder. createFile), skyportd in a lot of cases will cause 100% CPU usage and an OOM, probably crashing the system. This is fixed in 0.2.2.

The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk.
A flaw was found in Undertow. A buffer leak on the incoming WebSocket PONG message may lead to memory exhaustion. This flaw allows an attacker to cause a denial of service. The highest threat from this vulnerability is availability.
A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability.
There is a Uncontrolled Resource Consumption vulnerability in Huawei Smartphone.Successful exploitation of this vulnerability may lead to Screen projection application denial of service.
axios is vulnerable to Inefficient Regular Expression Complexity
The NPM package `braces`, versions prior to 3.0.3, fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. In `lib/parse.js,` if a malicious user sends "imbalanced braces" as input, the parsing will enter a loop, which will cause the program to start allocating heap memory without freeing it at any moment of the loop. Eventually, the JavaScript heap limit is reached, and the program will crash.
In Moodle, the file repository's URL parsing required additional recursion handling to mitigate the risk of recursion denial of service.
REXML is an XML toolkit for Ruby. The REXML gem before 3.3.2 has some DoS vulnerabilities when it parses an XML that has many specific characters such as whitespace character, `>]` and `]>`. The REXML gem 3.3.3 or later include the patches to fix these vulnerabilities.
A ReDoS (regular expression denial of service) flaw was found in the Segment is-email package before 1.0.1 for Node.js. An attacker that is able to provide crafted input to the isEmail(input) function may cause an application to consume an excessive amount of CPU.
Next.js is a React framework. A Denial of Service (DoS) condition was identified in Next.js. Exploitation of the bug can trigger a crash, affecting the availability of the server. his vulnerability was resolved in Next.js 13.5 and later.

PyXML: Hash table collisions CPU usage Denial of Service
An Uncontrolled Resource Consumption vulnerability in the H.323 ALG (Application Layer Gateway) of Juniper Networks Junos OS on SRX Series and MX Series with SPC3 and MS-MPC/MIC, allows an unauthenticated network-based attacker to send specific packets causing traffic loss leading to Denial of Service (DoS). Continued receipt and processing of these specific packets will sustain the Denial of Service condition. The memory usage can be monitored using the below command. user@host> show usp memory segment sha data objcache jsf This issue affects SRX Series and MX Series with SPC3 and MS-MPC/MIC: * 20.4 before 20.4R3-S10, * 21.2 before 21.2R3-S6, * 21.3 before 21.3R3-S5, * 21.4 before 21.4R3-S6, * 22.1 before 22.1R3-S4, * 22.2 before 22.2R3-S2, * 22.3 before 22.3R3-S1, * 22.4 before 22.4R3, * 23.2 before 23.2R2.

Windows Remote Desktop Gateway (RD Gateway) Denial of Service Vulnerability
BranchCache Denial of Service Vulnerability
.NET and Visual Studio Denial of Service Vulnerability
Grails is a framework used to build web applications with the Groovy programming language. A specially crafted web request can lead to a JVM crash or denial of service. Any Grails framework application using Grails data binding is vulnerable. This issue has been patched in version 3.3.17, 4.1.3, 5.3.4, 6.1.0.
OpenFGA is a flexible authorization/permission engine built for developers and inspired by Google Zanzibar. Affected versions of OpenFGA are vulnerable to a denial of service attack. When a number of `ListObjects` calls are executed, in some scenarios, those calls are not releasing resources even after a response has been sent, and given a sufficient call volume the service as a whole becomes unresponsive. This issue has been addressed in version 1.3.4 and the upgrade is considered backwards compatible. There are no known workarounds for this vulnerability.
An issue was discovered in Tor before 0.4.6.5, aka TROVE-2021-005. Hashing is mishandled for certain retrieval of circuit data. Consequently. an attacker can trigger the use of an attacker-chosen circuit ID to cause algorithm inefficiency.
A vulnerability in the memory management of Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper resource management when connection rates are high. An attacker could exploit this vulnerability by opening a significant number of connections on an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.
sqlparse is a non-validating SQL parser module for Python. In sqlparse versions 0.4.0 and 0.4.1 there is a regular Expression Denial of Service in sqlparse vulnerability. The regular expression may cause exponential backtracking on strings containing many repetitions of '\r\n' in SQL comments. Only the formatting feature that removes comments from SQL statements is affected by this regular expression. As a workaround don't use the sqlformat.format function with keyword strip_comments=True or the --strip-comments command line flag when using the sqlformat command line tool. The issues has been fixed in sqlparse 0.4.2.
