Cisco Talos’ Vulnerability Discovery & Research team recently disclosed ten vulnerabilities in BioSig Libbiosig, nine in Tenda AC6 Router, eight in SAIL, two in PDF-XChange Editor, and one in a Foxit PDF Reader. The vulnerabilities mentioned in this blog post have been patched by their respective vendors, all in

Citrix has released fixes to address three security flaws in NetScaler ADC and NetScaler Gateway, including one that it said has been actively exploited in the wild. The vulnerabilities in question are listed below - CVE-2025-7775 (CVSS score: 9.2) - Memory overflow vulnerability leading to Remote Code Execution and/or Denial-of-Service CVE-2025-7776 (CVSS score: 8.8) - Memory overflow

### Impact User control of the first argument of the addImage method results in CPU utilization and denial of service. If given the possibility to pass unsanitized image data or URLs to the addImage method, a user can provide a harmful PNG file that results in high CPU utilization and denial of service. Other affected methods are: `html`. Example payload: ```js import { jsPDF } from "jpsdf" const payload = new Uint8Array([117, 171, 90, 253, 166, 154, 105, 166, 154]) const doc = new jsPDF(); const startTime = performance.now(); try { doc.addImage(payload, "PNG", 10, 40, 180, 180, undefined, "SLOW"); } finally { const endTime = performance.now(); console.log(`Call to doc.addImage took ${endTime - startTime} milliseconds`); } ``` ### Patches The vulnerability was fixed in jsPDF 3.0.2. Upgrade to jspdf@>=3.0.2. In jspdf@>=3.0.2, invalid PNG files throw an Error instead of causing very long running loops. ### Workarounds Sanitize image data or URLs before passing it to the a...

## Summary Passing a geometry string containing only a colon (":") to montage -geometry leads GetGeometry() to set width/height to 0. Later, ThumbnailImage() divides by these zero dimensions, triggering a crash (SIGFPE/abort), resulting in a denial of service. ## Details **Root Cause** 1. `montage -geometry ":" ...` reaches `MagickCore/geometry.c:GetGeometry().` 2. `StringToDouble/InterpretLocaleValue` parses `":"` as `0.0;` then: https://github.com/ImageMagick/ImageMagick/blob/0ba1b587be17543b664f7ad538e9e51e0da59d17/MagickCore/geometry.c#L355 `WidthValue` (and/or `HeightValue)` is set with a zero dimension. 3. In MagickCore/resize.c:ThumbnailImage(), the code computes: https://github.com/ImageMagick/ImageMagick/blob/0ba1b587be17543b664f7ad538e9e51e0da59d17/MagickCore/resize.c#L4625-L4629 causing a division by zero and immediate crash. The issue is trivially triggerable without external input files (e.g., using `xc:white`). ### Reproduction Environment ``` Version: ImageMagick 7.1...

TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS Schneider Electric reports that the following products are affected: Modicon M340: All versions BMXNOR0200H Ethernet/Serial RTU Module: All versions BMXNGD0100 M580 Global Data module: All versions BMXNOC0401 Modicon M340 X80 Ethernet Communication modules: All versions BMXNOE0100 Modbus/TCP Ethernet Modicon M340 module: Versions prior to 3.60 BMXNOE0110 Modbus/TCP Ethernet Modicon M340 FactoryCast module: Versions prior to 6.80 3.2 VULNERABILITY OVERVIEW 3.2.1 IMPROPER INPUT VALIDATION CWE-20 Improper Input Validation vulnerability exists that could cause a Denial-of-Service when specially crafted FTP com...

A denial of service vulnerability exists in the JSONReader component of the run-llama/llama_index repository, specifically in version v0.12.37. The vulnerability is caused by uncontrolled recursion when parsing deeply nested JSON files, which can lead to Python hitting its maximum recursion depth limit. This results in high resource consumption and potential crashes of the Python process. The issue is resolved in version 0.12.38.

### Summary This issue: http://github.com/mlc-ai/xgrammar/issues/250 should have it's own security advisory. Since several tools accept and pass user supplied grammars to xgrammar, and it is so easy to trigger it seems like a High.

Adminer 4.8.1, when using Monolog for logging, allows a Denial of Service (memory consumption) via a crafted serialized payload (e.g., using s:1000000000), leading to a PHP Object Injection issue. Remote, unauthenticated attackers can trigger this by sending a malicious serialized object, which forces excessive memory usage, rendering Adminer’s interface unresponsive and causing a server-level DoS. While the server may recover after several minutes, multiple simultaneous requests can cause a complete crash requiring manual intervention.

Self-ReDoS (Regular expression Denial of Service) exists with Role Name search field of Kaleo Designer portlet JavaScript in Liferay Portal 7.4.0 through 7.4.3.131, and Liferay DXP 2024.Q4.0 through 2024.Q4.1, 2024.Q3.0 through 2024.Q3.13, 2024.Q2.1 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.20 and 7.4 GA through update 92, which allows authenticated users with permissions to update Kaleo Workflows to enter a malicious Regex pattern causing their browser to hang for a very long time.

Dear Maintainers, I am writing to you on behalf of the Tencent AI Sec. We have identified a potential vulnerability in one of your products and would like to report it to you for further investigation and mitigation. ### Summary The `jk` parameter is received in pyLoad CNL Blueprint. Due to the lack of `jk` parameter verification, the `jk` parameter input by the user is directly determined as dykpy.evaljs(), resulting in the server CPU being fully occupied and the web-ui becoming unresponsive. ### Details - Endpoint: flash/addcrypted2 - affected file: https://github.com/pyload/pyload/blob/develop/src/pyload/webui/app/blueprints/cnl_blueprint.py#L123 https://github.com/pyload/pyload/blob/develop/src/pyload/core/utils/misc.py#L42 affected code ```python @bp.route("/flash/addcrypted2", methods=["POST"], endpoint="addcrypted2") @local_check def addcrypted2(): package = flask.request.form.get( "package", flask.request.form.get("source", flask.request.form.get("referer")) ...
