GHSA-C2V2-7RCG-2CH7
Vulnerability from github – Published: 2020-09-01 15:17 – Updated: 2021-01-14 15:58The ansi2html package is affected by a regular expression denial of service vulnerability when certain types of user input is passed in.
Proof of concept
var ansi2html = require('ansi2html')
var start = process.hrtime();
ansi2html("[1111111111111111111111;0000000000000000000000");
console.log(process.hrtime(start));
start = process.hrtime();
ansi2html("[1111111111111111111111;00000000000000000000000");
console.log(process.hrtime(start));
start = process.hrtime();
ansi2html("[1111111111111111111111;000000000000000000000000");
console.log(process.hrtime(start));
start = process.hrtime();
ansi2html("[1111111111111111111111;0000000000000000000000000000");
console.log(process.hrtime(start));
Results of the above

Recommendation
At the time of this writing, February 2018, all versions of ansi2html remain vulnerable, and the package has not been updated for 4 years.
In order to use this package safely, it is necessary to avoid passing user input to the package, or to limit the size of the input string to a size with a parse time you find acceptable. Unfortunately, the match time grows at quite a small character count, so it is unlikely for it to both allow strings of a useful size while protecting against the denial of service attack.
In the case that user input of significant length must be parsed by ansi2html, the best mitigation is to use an alternative module that is actively maintained and provides similar functionality. There are [multiple modules fitting this criteria available on npm.]available on npm

GHSA-C33X-XQRF-C478
Vulnerability from github – Published: 2024-04-02 14:16 – Updated: 2024-04-05 18:53An attacker can cause its peer to run out of memory by sending a large number of NEW_CONNECTION_ID frames that retire old connection IDs. The receiver is supposed to respond to each retirement frame with a RETIRE_CONNECTION_ID frame. The attacker can prevent the receiver from sending out (the vast majority of) these RETIRE_CONNECTION_ID frames by collapsing the peers congestion window (by selectively acknowledging received packets) and by manipulating the peer's RTT estimate.
I published a more detailed description of the attack and its mitigation in this blog post: https://seemann.io/posts/2024-03-19-exploiting-quics-connection-id-management/. I also presented this attack in the IETF QUIC working group session at IETF 119: https://youtu.be/JqXtYcZAtIA?si=nJ31QKLBSTRXY35U&t=3683
There's no way to mitigate this attack, please update quic-go to a version that contains the fix.

GHSA-C392-WRGW-JJFW
Vulnerability from github – Published: 2025-03-19 18:30 – Updated: 2025-03-20 13:18A flaw was found in the Hive hibernation controller component of OpenShift Dedicated. The ClusterDeployment.hive.openshift.io/v1 resource can be created with the spec.installed field set to true, regardless of the installation status, and a positive timespan for the spec.hibernateAfter value. If a ClusterSync.hiveinternal.openshift.io/v1alpha1 resource is also created, the hive hibernation controller will enter the reconciliation loop leading to a panic when accessing a non-existing field in the ClusterDeployment’s status section, resulting in a denial of service.

Mitigation
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.
Mitigation
- Mitigation of resource exhaustion attacks requires that the target system either:
- The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
- The second solution is simply difficult to effectively institute -- and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
- recognizes the attack and denies that user further access for a given amount of time, or
- uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Mitigation
Ensure that protocols have specific limits of scale placed on them.
Mitigation
Ensure that all failures in resource allocation place the system into a safe posture.
CAPEC-147: XML Ping of the Death
An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.
CAPEC-227: Sustained Client Engagement
An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.
CAPEC-492: Regular Expression Exponential Blowup
An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
