Python 安全漏洞
Python is an open source, object-oriented programming language from the Python Foundation. The language is extensible, supports modules and packages, and supports multiple platforms. A security vulnerability exists in Python that stems from a quadratic complexity issue when processing specially...
cmark-gfm: Quadratic complexity bugs may lead to a denial of service
A flaw was found in CommonMarker. A polynomial time complexity issue in cmark-gfm may lead to unbounded resource exhaustion and subsequent denial of service...
ALSA-2025:8427 Moderate: pandoc security update
Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read several dialects of Markdown and subsets of HTML, reStructuredText, LaTeX, DocBook, JATS, MediaWiki markup, TWiki markup, TikiWiki markup, Creole 1.0, Haddock...
The Tangent Space Attack
We propose a new method for retrieving the algebraic structure of a generic alternant code given an arbitrary generator matrix, provided certain conditions are met. We then discuss how this challenges the security of the McEliece cryptosystem instantiated with this family of codes. The central...
Denial Of Service (DoS)
vllm is vulnerable to a Denial Of Service DoS. The vulnerability is due to inefficient list concatenation operations and also dynamic replacement of placeholder tokens with repeated tokens based on precomputed lengths, allowing an attacker to trigger resource exhaustion by exploiting the quadrati...
Langroid Allows XXE Injection via XMLToolMessage
Summary A LLM application leveraging XMLToolMessage class may be exposed to untrusted XML input that could result in DoS and/or exposing local files with sensitive information. Details XMLToolMessage uses lxml without safeguards:...
CVE-2025-46560 vLLM phi4mm: Quadratic Time Complexity in Input Token Processing leads to denial of service
vLLM is a high-throughput and memory-efficient inference and serving engine for LLMs. Versions starting from 0.8.0 and prior to 0.8.5 are affected by a critical performance vulnerability in the input preprocessing logic of the multimodal tokenizer. The code dynamically replaces placeholder tokens...
