A uncontrolled resource consumption in Fortinet FortiWeb version 6.4.1 and below, 6.3.15 and below allows an unauthenticated attacker to make the httpsd daemon unresponsive via huge HTTP packets
In the Linux kernel, the following vulnerability has been resolved: net: sched: fix memory leak in tcindex_partial_destroy_work Syzbot reported memory leak in tcindex_set_parms(). The problem was in non-freed perfect hash in tcindex_partial_destroy_work(). In tcindex_set_parms() new tcindex_data is allocated and some fields from old one are copied to new one, but not the perfect hash. Since tcindex_partial_destroy_work() is the destroy function for old tcindex_data, we need to free perfect hash to avoid memory leak.
modern-async is an open source JavaScript tooling library for asynchronous operations using async/await and promises. In affected versions a bug affecting two of the functions in this library: forEachSeries and forEachLimit. They should limit the concurrency of some actions but, in practice, they don't. Any code calling these functions will be written thinking they would limit the concurrency but they won't. This could lead to potential security issues in other projects. The problem has been patched in 1.0.4. There is no workaround.
The etcd package distributed with the Red Hat OpenStack platform has an incomplete fix for CVE-2023-39325/CVE-2023-44487, known as Rapid Reset. This issue occurs because the etcd package in the Red Hat OpenStack platform is using http://golang.org/x/net/http2 instead of the one provided by Red Hat Enterprise Linux versions, meaning it should be updated at compile time instead.
The WBM web application on firmwares prior to 03.02.02 and 03.01.07 on the WAGO PFC100 and PFC2000, respectively, runs on a lighttpd web server and makes use of the FastCGI module, which is intended to provide high performance for all Internet applications without the penalties of Web server APIs. However, the default configuration of this module appears to limit the number of concurrent php-cgi processes to two, which can be abused to cause a denial of service of the entire web server. This affects WAGO PFC200 Firmware version 03.00.39(12) and version 03.01.07(13), and WAGO PFC100 Firmware version 03.00.39(12) and version 03.02.02(14).
Katello has a Denial of Service vulnerability in API OAuth authentication
In Node.js including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1, an attacker can cause a Denial of Service (DoS) by establishing an HTTP or HTTPS connection in keep-alive mode and by sending headers very slowly. This keeps the connection and associated resources alive for a long period of time. Potential attacks are mitigated by the use of a load balancer or other proxy layer. This vulnerability is an extension of CVE-2018-12121, addressed in November and impacts all active Node.js release lines including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1.
The Schneider Electric M340 PLC modules allow remote attackers to cause a denial of service (resource consumption) via unspecified vectors. NOTE: the vendor reportedly disputes this issue because it "could not be duplicated" and "an attacker could not remotely exploit this observed behavior to deny PLC control functions.
The socket implementation in net/core/sock.c in the Linux kernel before 2.6.35 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service by sending a large amount of network traffic, related to the sk_add_backlog function and the sk_rmem_alloc socket field. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-4251.
The etcd package distributed with the Red Hat OpenStack platform has an incomplete fix for CVE-2022-41723. This issue occurs because the etcd package in the Red Hat OpenStack platform is using http://golang.org/x/net/http2 instead of the one provided by Red Hat Enterprise Linux versions, meaning it should be updated at compile time instead.
Fluentd collects events from various data sources and writes them to files to help unify logging infrastructure. The parser_apache2 plugin in Fluentd v0.14.14 to v1.14.1 suffers from a regular expression denial of service (ReDoS) vulnerability. A broken apache log with a certain pattern of string can spend too much time in a regular expression, resulting in the potential for a DoS attack. This issue is patched in version 1.14.2 There are two workarounds available. Either don't use parser_apache2 for parsing logs (which cannot guarantee generated by Apache), or put patched version of parser_apache2.rb into /etc/fluent/plugin directory (or any other directories specified by the environment variable `FLUENT_PLUGIN` or `--plugin` option of fluentd).
A denial of service flaw was found in miekg-dns before 1.0.4. A remote attacker could use carefully timed TCP packets to block the DNS server from accepting new connections.
charset 1.0.0 and below are vulnerable to regular expression denial of service. Input of around 50k characters is required for a slow down of around 2 seconds. Unless node was compiled using the -DHTTP_MAX_HEADER_SIZE= option the default header max length is 80kb, so the impact of the ReDoS is relatively low.

A vulnerability in SSL/TLS message handler for Cisco Adaptive Security Appliance (ASA) Software and Cisco 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 exists because incoming SSL/TLS packets are not properly processed. An attacker could exploit this vulnerability by sending a crafted SSL/TLS packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.

BranchCache Denial of Service Vulnerability
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.

An unauthenticated, remote attacker may make the LDAP server not respond to the client's request by controlling the LDAP server. Due to improper management of LDAP connection resource, a successful exploit may cause the connection resource exhausted of the LDAP client.

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.

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.
fast-xml-parser is an open source, pure javascript xml parser. a ReDOS exists on currency.js. This vulnerability is fixed in 4.4.1.
Decamelize is used to convert a dash/dot/underscore/space separated string to camelCase. Decamelize 1.1.0 through 1.1.1 uses regular expressions to evaluate a string and takes unescaped separator values, which can be used to create a denial of service attack.
