Background
The isofs package is a component of the Linux Kernel, which is responsible for handling ISO 9660 file systems. ISO 9660 is a standard file system for optical disc media, such as CDs and DVDs. The isofs package provides support for reading and writing ISO 9660 file systems in the Linux operating system. It is widely used in various Linux distributions and is an integral part of the kernel. However, a vulnerability has been discovered in the isofs package that can lead to out of bound access when processing corrupted isofs images.
Vulnerability Detail
