There is a speculative pointer dereferencing issue in the Linux kernel, specifically with the doprlimit function. The value of the resource argument is controlled and is used in pointer arithmetic for the ‘rlim’ variable. This can lead to the leakage of its contents. We recommend upgrading to a...

Astra Linux – Vulnerability in openimageio

There are multiple code execution vulnerabilities in the IFFOutput::close function of the OpenImageIO Project, specifically in OpenImageIO v2.4.4.2. A specially crafted ImageOutput Object can lead to a heap buffer overflow. An attacker can provide malicious input to exploit these vulnerabilities...
