CVE-2012-4024: Squashfs Project Squashfs

Medium severity, CVSS 6.8. EPSS: 4% chance of exploitation in the next 30 days.

Stack-based buffer overflow in the get_component function in unsquashfs.c in unsquashfs in Squashfs 4.2 and earlier allows remote attackers to execute arbitrary code via a crafted list file (aka a crafted file for the -ef option). NOTE: probably in most cases, the list file is a trusted file constructed by the program's user; however, there are some realistic situations in which a list file would be obtained from an untrusted remote source.

Affected products

• Squashfs Project Squashfs: up to and including 4.2
