CVSS v3.1 |
| A denial of service (DoS) vulnerability has been identified in the JavaScript library microlight version 0.0.7. This library, used for syntax highlighting, does not limit the size of textual content it processes in HTML elements with the microlight class. When excessively large content (e.g., 100 million characters) is processed, the reset function in microlight.js consumes excessive memory and CPU resources, causing browser crashes or unresponsiveness. An attacker can exploit this vulnerability by tricking a user into visiting a malicious web page containing a microlight element with large content, resulting in a denial of service. NOTE: this is disputed by multiple parties because a large amount of memory and CPU resources is expected to be needed for content of that size. |
| 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. |
| 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. |
| Stalwart is a mail and collaboration server. Starting in version 0.12.0 and prior to version 0.13.3, a memory exhaustion vulnerability exists in Stalwart's CalDAV implementation that allows authenticated attackers to cause denial-of-service by triggering unbounded memory consumption through recurring event expansion. An authenticated attacker can crash the Stalwart server by creating recurring events with large payloads and triggering their expansion through CalDAV REPORT requests. A single malicious request expanding 300 events with 1000-character descriptions can consume up to 2 GB of memory. The vulnerability exists in the `ArchivedCalendarEventData.expand` function, which processes CalDAV `REPORT` requests with event expansion. When a client requests recurring events in their expanded form using the `<C:expand>` element, the server stores all expanded event instances in memory without enforcing size limits. Users should upgrade to Stalwart version 0.13.3 or later to receive a fix. If immediate upgrading is not possible, implement memory limits at the container/system level; monitor server memory usage for unusual spikes; consider rate limiting CalDAV REPORT requests; and restrict CalDAV access to trusted users only. |
| The ParseAddress function constructs domain-literal address components through repeated string concatenation. When parsing large domain-literal components, this can cause excessive CPU consumption. |
| Vickey is a Misskey-based microblogging platform. A vulnerability exists in Vickey prior to version 2025.10.0 where unexpired email confirmation links can be reused multiple times to send repeated confirmation emails to a verified email address. Under certain conditions, a verified email address could receive repeated confirmation messages if the verification link was accessed multiple times. This issue may result in unintended email traffic but does not expose user data. The issue was addressed in version 2025.10.0 by improving validation logic to ensure verification links behave as expected after completion. |
| Insufficiently specific bounds checking on authorization header could lead to denial of service in the Temporal server on all platforms due to excessive memory allocation.This issue affects all platforms and versions of OSS Server prior to 1.26.3, 1.27.3, and 1.28.1 (i.e., fixed in 1.26.3, 1.27.3, and 1.28.1 and later). Temporal Cloud services are not impacted. |
| Allocation of Resources Without Limits or Throttling vulnerability in Legion of the Bouncy Castle Inc. BC Java bcprov on All (API modules), Legion of the Bouncy Castle Inc. BC-FJA bc-fips on All allows Excessive Allocation. This vulnerability is associated with program files https://github.com/bcgit/bc-java/blob/main/core/src/main/java/org/bouncycastle/asn1/ASN1ObjectIdenti... https://github.com/bcgit/bc-java/blob/main/core/src/main/java/org/bouncycastle/asn1/ASN1ObjectIdentifier.Java .
This issue affects BC Java: from 1.0 through 1.77; BC-FJA: from 1.0.0 through 1.0.2.5, from 2.0.0 through 2.0.1. |
| A vulnerability in danswer-ai/danswer version 0.9.0 allows for denial of service through memory exhaustion. The issue arises from the use of a vulnerable version of the starlette package (<=0.49) via fastapi, which was patched in fastapi version 0.115.3. The vulnerability can be exploited by sending multiple requests to the /auth/saml/callback endpoint, leading to uncontrolled memory consumption and eventual denial of service. |
| A denial-of-service (DoS) vulnerability in Palo Alto Networks Prisma® SD-WAN ION devices enables an unauthenticated attacker in a network adjacent to a Prisma SD-WAN ION device to disrupt the packet processing capabilities of the device by sending a burst of crafted packets to that device. |
| An Allocation of Resources Without Limits or Throttling vulnerability in Cesanta Frozen versions less than 1.7 allows an attacker to induce a crash of the component embedding the library by supplying a maliciously crafted JSON as input. |
| A vulnerability has been identified within Rancher Manager in which it
did not enforce request body size limits on certain public
(unauthenticated) and authenticated API endpoints. This allows a
malicious user to exploit this by sending excessively large payloads,
which are fully loaded into memory during processing, leading to Denial of Service (DoS). |
| Fetch FTP Client 5.8.2 contains a denial of service vulnerability that allows attackers to trigger 100% CPU consumption by sending long server responses. Attackers can send specially crafted FTP server responses exceeding 2K bytes to cause excessive resource utilization and potentially crash the application. |
| In Matter (aka connectedhomeip or Project CHIP) through 1.4.0.0 before e3277eb, unlimited user label appends in a userlabel cluster can lead to a denial of service (resource exhaustion). |
| In AXESS ACS (Auto Configuration Server) through 5.2.0, unsanitized user input in the TR069 API allows remote unauthenticated attackers to cause a permanent Denial of Service via crafted TR069 requests on TCP port 9675 or 7547. Rebooting does not resolve the permanent Denial of Service. |
| An allocation-size-too-big bug in the component /imagebuf.cpp of OpenImageIO v3.1.0.0dev may cause a Denial of Service (DoS) when the program to requests to allocate too much space. |
| python-multipart is a streaming multipart parser for Python. When parsing form data, python-multipart skips line breaks (CR \r or LF \n) in front of the first boundary and any tailing bytes after the last boundary. This happens one byte at a time and emits a log event each time, which may cause excessive logging for certain inputs. An attacker could abuse this by sending a malicious request with lots of data before the first or after the last boundary, causing high CPU load and stalling the processing thread for a significant amount of time. In case of ASGI application, this could stall the event loop and prevent other requests from being processed, resulting in a denial of service (DoS). This vulnerability is fixed in 0.0.18. |
| Bitcoin-Qt in Bitcoin Core before 0.20.0 allows remote attackers to cause a denial of service (memory consumption and application crash) via a BIP21 r parameter for a URL that has a large file. |
| 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. |
| A flaw was found in the virtio-crypto device of QEMU. A malicious guest operating system can exploit a missing length limit in the AKCIPHER path, leading to uncontrolled memory allocation. This can result in a denial of service (DoS) on the host system by causing the QEMU process to terminate unexpectedly. |
