## Description

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.
