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, commonly used for CD-ROMs. The isofs package provides support for reading and writing ISO 9660 file systems in the Linux operating system. However, a vulnerability has been discovered in the isofs package that allows for out of bound access when processing corrupted isofs images.
Vulnerability Detail
The vulnerability in the isofs package arises from a lack of proper bounds checking when handling corrupted isofs images. An attacker can exploit this vulnerability by crafting a malicious isofs image that triggers an out of bound access. This can lead to various consequences, including potential information disclosure, denial of service, or even remote code execution. The vulnerability has been fixed in Linux Kernel version v4.14.255 by commit afbd40f425227e661d991757e11cc4db024e761f.
