View CSAF 1. EXECUTIVE SUMMARY CVSS v4 8.7 ATTENTION: Exploitable remotely/low attack complexity Vendor: Rockwell Automation Equipment: ArmorStart AOP Vulnerability: Uncaught Exception 2. RISK EVALUATION Successful exploitation of this vulnerability could allow an attacker to cause a denial-of-service condition on the affected product. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following Rockwell Automation products are affected: ArmorStart AOP: Version V2.05.07 and prior 3.2 VULNERABILITY OVERVIEW 3.2.1 Uncaught Exception CWE-248 A security issue exists within the Studio 5000 Logix Designer add-on profile (AOP) for the ArmorStart Classic distributed motor controller, resulting in a denial-of-service. This vulnerability is possible due to the input of invalid values into Component Object Model (COM) methods. CVE-2025-9437 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). A CVS...

### Summary `sveltekit-superforms` v2.27.3 and prior are susceptible to a prototype pollution vulnerability within the `parseFormData` function of `formData.js`. An attacker can inject string and array properties into `Object.prototype`, leading to denial of service, type confusion, and potential remote code execution in downstream applications that rely on polluted objects. ### Details Superforms is a SvelteKit form library for server and client form validation. Under normal operation, form validation is performed by calling the the `superValidate` function, with the submitted form data and a form schema as arguments: ```js // https://superforms.rocks/get-started#posting-data const form = await superValidate(request, your_adapter(schema)); ``` Within the `superValidate` function, a call is made to `parseRequest` in order to parse the user's input. `parseRequest` then calls into `parseFormData`, which in turn looks for the presence of `__superform_json` in the form parameters. If `_...

### Impact During deserialization of ECDSA and EdDSA signatures gnark-crypto did not check that the values are in the range `[1, n-1]` with `n` being the corresponding modulus (either base field modulus in case of `R` in EdDSA, and scalar field modulus in case of `s,r` in ECDSA and `s` in EdDSA). As this also allowed zero inputs, then it was possible to craft a signature which lead to null pointer dereference, leading to denial-of-service of an application. This also enabled weak signature malleability when the users assumed uniqueness of the serialized signatures (but not the underlying modulo reduced values). We are not aware of any users impacted by the bug. The implemented signature schemes in gnark-crypto complement the in-circuit versions in gnark, allowing to have end-to-end tests. ### Patches The issue was patched in PR #449. The fix returns an error during deserialization if the values do not belong to the ranges `[1, n-1]`. The fix is included in release v0.12.0 and upwa...

# Microsoft Security Advisory CVE-2025-55247 | .NET Denial of Service Vulnerability ## <a name="executive-summary"></a>Executive summary Microsoft is releasing this security advisory to provide information about a vulnerability in .NET 8.0.xxx, .NET 9.0.xxx and .NET 10.0.xxx. This advisory also provides guidance on what developers can do to update their environments to remove this vulnerability. A vulnerability exists in .NET where predictable paths for MSBuild's temporary directories on Linux let another user create the directories ahead of MSBuild, leading to DoS of builds. This only affects .NET on Linux operating systems. ## Announcement Announcement for this issue can be found at https://github.com/dotnet/announcements/issues/370 ### <a name="mitigation-factors"></a>Mitigation factors Projects which do not utilize the [DownloadFile](https://learn.microsoft.com/visualstudio/msbuild/downloadfile-task) build task are not susceptible to this vulnerability. ## <a name="affect...

### Impact An uncaught panic triggered by malformed input to `alloy_dyn_abi::TypedData` could lead to a denial-of-service (DoS) via `eip712_signing_hash()`. Software with high availability requirements such as network services may be particularly impacted. If in use, external auto-restarting mechanisms can partially mitigate the availability issues unless repeated attacks are possible. ### Patches The vulnerability was patched by adding a check to ensure the element is not empty before accessing its first element; an error is returned if it is empty. The fix is included in version [`v1.4.1`](https://crates.io/crates/alloy-dyn-abi/1.4.1) and backported to [`v0.8.26`](https://crates.io/crates/alloy-dyn-abi/0.8.26). ### Workarounds There is no known workaround that mitigates the vulnerability. Upgrading to a patched version is the recommended course of action. ### Reported by Christian Reitter & Zeke Mostov from [Turnkey](https://www.turnkey.com/)

Microsoft on Tuesday released fixes for a whopping 183 security flaws spanning its products, including three vulnerabilities that have come under active exploitation in the wild, as the tech giant officially ended support for its Windows 10 operating system unless the PCs are enrolled in the Extended Security Updates (ESU) program. Of the 183 vulnerabilities, eight of them are non-Microsoft

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-w3q9-fxm7-j8fq. This link is maintained to preserve external references. ### Original Description Improper link resolution before file access ('link following') in .NET allows an authorized attacker to elevate privileges locally.
