## Summary [Amazon.IonDotnet (ion-dotnet)](https://github.com/amazon-ion/ion-dotnet) is a .NET library with an implementation of the [Ion data serialization format](https://amazon-ion.github.io/ion-docs/). An issue exists in Amazon.IonDotnet and the RawBinaryReader class where, under certain conditions, an actor could trigger an infinite loop condition. ## Impact When reading binary Ion data through Amazon.IonDotnet using the RawBinaryReader class, Amazon.IonDotnet does not check the number of bytes read from the underlying stream while deserializing the binary format. If the Ion data is malformed or truncated, this triggers an infinite loop condition that could potentially result in a denial of service. **Impacted versions: <=1.3.0** ## Patches This issue has been addressed in Amazon.IonDotnet version [1.3.1](https://github.com/amazon-ion/ion-dotnet/releases/tag/v1.3.1). We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorp...

Cybersecurity researchers are warning of continued risks posed by a distributed denial-of-service (DDoS) malware known as XorDDoS, with 71.3 percent of the attacks between November 2023 and February 2025 targeting the United States. "From 2020 to 2023, the XorDDoS trojan has increased significantly in prevalence," Cisco Talos researcher Joey Chen said in a Thursday analysis.

Cisco Talos observed the ongoing global spread of the XorDDoS malware, predominantly targeting the United States, with evidence suggesting Chinese-speaking operators are using sophisticated tools to orchestrate widespread attacks.

A vulnerability, which was classified as problematic, was found in PyTorch 2.6.0. Affected is the function torch.nn.functional.ctc_loss of the file aten/src/ATen/native/LossCTC.cpp. The manipulation leads to denial of service. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The name of the patch is 46fc5d8e360127361211cb237d5f9eef0223e567. It is recommended to apply a patch to fix this issue.

Cisco Talos’ Vulnerability Discovery & Research team recently disclosed three vulnerabilities found in Eclipse ThreadX and four vulnerabilities in STMicroelectronics.    The vulnerabilities mentioned in this blog post have been patched by their respective vendors, all in adherence to Cisco’s third-party vulnerability disclosure policy.

### Impact This report is to highlight a vulnerability in XGrammar, a library used by the structured output feature in vLLM. The XGrammar advisory is here: https://github.com/mlc-ai/xgrammar/security/advisories/GHSA-389x-67px-mjg3 The [xgrammar](https://xgrammar.mlc.ai/docs/) library is the default backend used by vLLM to support structured output (a.k.a. guided decoding). Xgrammar provides a required, built-in cache for its compiled grammars stored in RAM. xgrammar is available by default through the OpenAI compatible API server with both the V0 and V1 engines. A malicious user can send a stream of very short decoding requests with unique schemas, resulting in an addition to the cache for each request. This can result in a Denial of Service by consuming all of the system's RAM. Note that even if vLLM was configured to use a different backend by default, it is still possible to choose xgrammar on a per-request basis using the `guided_decoding_backend` key of the `extra_body` field ...
