PHP: PHP: Denial of Service via improper handling of signed characters in ctype functions

A flaw was found in PHP. Some functions, including urldecode, incorrectly pass signed characters to character type ctype functions. On certain systems, this can lead to accessing memory with a negative offset. This vulnerability can be exploited by an attacker to trigger a denial of service DoS,...

SUSE CVE-2025-8194

There is a defect in the CPython “tarfile” module affecting the “TarFile” extraction and entry enumeration APIs. The tar implementation would process tar archives with negative offsets without error, resulting in an infinite loop and deadlock during the parsing of maliciously crafted tar archives...

ONNX: Malicious ONNX models can crash servers by exploiting unprotected object settings.

Summary The ExternalDataInfo class in ONNX was using Python’s setattr function to load metadata like file paths or data lengths directly from an ONNX model file. The problem? It didn’t check if the "keys" in the file were valid. Because it blindly trusted the file, an attacker could craft a...
