ImageSharp Triggers an Infinite Loop in its GIF Decoder When Skipping Malformed Comment Extension Blocks

ImageSharp is a 2D graphics library. In versions below 2.1.11 and 3.0.0 through 3.1.10, a specially crafted GIF file containing a malformed comment extension block (with a missing block terminator) can cause the ImageSharp GIF decoder to enter an infinite loop while attempting to skip the block. This leads to a denial of service. Applications processing untrusted GIF input should upgrade to a patched version. This issue is fixed in versions 2.1.11 and 3.1.11.

Ruby SAML DOS vulnerability with large SAML response

The Ruby SAML library is for implementing the client side of a SAML authorization. In versions 1.18.0 and below, a denial-of-service vulnerability exists in ruby-saml even with the message_max_bytesize setting configured. The vulnerability occurs because the SAML response is validated for Base64 format prior to checking the message size, leading to potential resource exhaustion. This is fixed in version 1.18.1.

Denial of service due to allocation of resources without limits. The following products are affected: Acronis Cyber Protect Cloud Agent (Windows) before build 39904, Acronis Cyber Protect 17 (Windows) before build 41186.

py-libp2p before 0.2.3 allows a peer to cause a denial of service (resource consumption) via a large RSA key.

HTTP Service DoS Vulnerability

An unauthenticated remote attacker can cause a Denial of Service by sending a large number of requests to the http service on port 80.

OpenTelemetry .NET has a Denial of Service (DoS) Vulnerability in API Package

OpenTelemetry dotnet is a dotnet telemetry framework. A vulnerability in OpenTelemetry.Api package 1.10.0 to 1.11.1 could cause a Denial of Service (DoS) when a tracestate and traceparent header is received. Even if an application does not explicitly use trace context propagation, receiving these headers can still trigger high CPU usage. This issue impacts any application accessible over the web or backend services that process HTTP requests containing a tracestate header. Application may experience excessive resource consumption, leading to increased latency, degraded performance, or downtime. This vulnerability is fixed in 1.11.2.

Go JOSE's Parsing Vulnerable to Denial of Service

Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption (JWE), JSON Web Signature (JWS), and JSON Web Token (JWT) standards. In versions on the 4.x branch prior to version 4.0.5, when parsing compact JWS or JWE input, Go JOSE could use excessive memory. The code used strings.Split(token, ".") to split JWT tokens, which is vulnerable to excessive memory consumption when processing maliciously crafted tokens with a large number of `.` characters. An attacker could exploit this by sending numerous malformed tokens, leading to memory exhaustion and a Denial of Service. Version 4.0.5 fixes this issue. As a workaround, applications could pre-validate that payloads passed to Go JOSE do not contain an excessive number of `.` characters.

@fastify/multipart vulnerable to unlimited consumption of resources

@fastify/multipart is a Fastify plugin for parsing the multipart content-type. Prior to versions 8.3.1 and 9.0.3, the `saveRequestFiles` function does not delete the uploaded temporary files when user cancels the request. The issue is fixed in versions 8.3.1 and 9.0.3. As a workaround, do not use `saveRequestFiles`.

A denial-of-service vulnerability due to improper prioritization of network traffic over protection mechanism exists in Relion 670/650 and SAM600-IO series device that if exploited could potentially cause critical functions like LDCM (Line Distance Communication Module) to malfunction.

File Station 5

An allocation of resources without limits or throttling vulnerability has been reported to affect File Station 5. If a remote attacker gains a user account, they can then exploit the vulnerability to prevent other systems, applications, or processes from accessing the same type of resource. We have already fixed the vulnerability in the following version: File Station 5 5.5.6.4847 and later

Lack of rate-limiting in password change mechanism in CyberArk Endpoint Privilege Manager

Application does not limit the number or frequency of user interactions, such as the number of incoming requests. At the "/EPMUI/VfManager.asmx/ChangePassword" endpoint it is possible to perform a brute force attack on the current password in use. This issue affects CyberArk Endpoint Privilege Manager in SaaS version 24.7.1. The status of other versions is unknown. After multiple attempts to contact the vendor we did not receive any answer.

AuntyFey Smart Combination Lock BLE Connection Flood DoS

AuntyFey Smart Combination Lock firmware versions as of 2025-12-24 contain a vulnerability that allows an unauthenticated attacker within Bluetooth Low Energy (BLE) range to cause a denial of service by repeatedly initiating BLE connections. Sustained connection attempts interrupt keypad authentication input and repeatedly force the device into lockout states, preventing legitimate users from unlocking the device.

Kubevirt: kubevirt: vm administration denial of service via guest agent

A flaw was found in kubevirt. A user within a virtual machine (VM), if the guest agent is active, can exploit this by causing the agent to report an excessive number of network interfaces. This action can overwhelm the system's ability to store VM configuration updates, effectively blocking changes to the Virtual Machine Instance (VMI). This allows the VM user to restrict the VM administrator's ability to manage the VM, leading to a denial of service for administrative operations.

Güralp Systems Fortimus Series, Minimus Series, and Certimus Series have an Allocation of Resources Without Limits or Throttling vulnerability

A vulnerability in the web interface of the Güralp Fortimus Series, Minimus Series and Certimus Series allows an unauthenticated attacker with network access to send specially-crafted HTTP requests that can cause the web service process to deliberately restart. Although this mechanism limits the impact of the attack, it results in a brief denial-of-service condition during the restart.

Digiwin｜EasyFlow GP - Denial of service

EasyFlow GP developed by Digiwin has a Denial of service vulnerability, allowing unauthenticated remote attackers to send specific requests that result in denial of web service.

Allocation of Resources Without Limits or Throttling in Shelly Pro 4PM

Allocation of Resources Without Limits or Throttling vulnerability in Shelly Pro 4PM (before v1.6) allows Excessive Allocation via network.

Vulnerability on Automation Runtime my cause DoS Conditions

An Allocation of Resources Without Limits or Throttling vulnerability in the ANSL-Server component of B&R Automation Runtime versions prior to 6.5 and prior to R4.93 could be exploited by an unauthenti-cated attacker on the network to win a race condition, resulting in permanent denial-of-service (DoS) conditions on affected devices.

rPGP Potential Resource Exhaustion when handling Untrusted Messages

rPGP is a pure Rust implementation of OpenPGP. Prior to 0.14.1, rPGP allows attackers to trigger resource exhaustion vulnerabilities in rpgp by providing crafted messages. This affects general message parsing and decryption with symmetric keys.

Password Pusher's rate limiter can be bypassed by forging proxy headers

Password Pusher, an open source application to communicate sensitive information over the web, comes with a configurable rate limiter. In versions prior to v1.49.0, the rate limiter could be bypassed by forging proxy headers allowing bad actors to send unlimited traffic to the site potentially causing a denial of service. In v1.49.0, a fix was implemented to only authorize proxies on local IPs which resolves this issue. As a workaround, one may add rules to one's proxy and/or firewall to not accept external proxy headers such as `X-Forwarded-*` from clients.

An issue in how XINJE XD5E-24R and XL5E-16T v3.5.3b handles TCP protocol messages allows attackers to cause a Denial of Service (DoS) via a crafted TCP message.
