CVE-2011-5325 [HIGH] BusyBox vulnerabilities
Title: BusyBox vulnerabilities
Summary: Several security issues were fixed in BusyBox.
Tyler Hicks discovered that BusyBox incorrectly handled symlinks inside tar
archives. If a user or automated system were tricked into processing a
specially crafted tar archive, a remote attacker could overwrite arbitrary
files outside of the current directory. This issue only affected Ubuntu
14.04 LTS and Ubuntu 16.04 LTS. (CVE-2011-5325)
Mathias Krause discovered that BusyBox incorrectly handled kernel module
loading restrictions. A local attacker could possibly use this issue to
bypass intended restrictions. This issue only affected Ubuntu 14.04 LTS.

CVE-2014-9645 busybox: unprivileged arbitrary module load via basename abuse
Matthias Krause reports:
modprobe uses the "basename" of the module argument as the module to load, as
can be seen here:
bbox:~# lsmod | grep vfat
bbox:~# modprobe foo/bar/baz/vfat
bbox:~# lsmod | grep vfat
vfat 17135 0
fat 61984 1 vfat
bbox:~# find /lib/modules/`uname -r` -name vfat.ko
/lib/modules/3.18.0-rc5+/vfat.ko
It should instead fail to load the module -- actually fail to *find* the
module.
This can even be abused to load arbitrary modules by nullifying enforced module
prefixes some of the Linux kernel's subsystems try to apply to prevent just
that:
bbox:~# lsmod | grep usb
bbox:~# ifconfig /usbserial up
ifconfig: SIOCGIFFLAGS: No such device
bbox:~# lsmod | grep usb
usbserial 32201 0

One Bad Apple Spoils the Barrel: Understanding the Security Risks Introduced by Third-Party Components in IoT Firmware
## Abstract
Currently, the development of IoT firmware heavily depends on third-party components (TPCs) to improve development efficiency. Nevertheless, TPCs are not secure, and the vulnerabilities in TPCs will influence the security of IoT firmware. Existing works pay less attention to the vulnerabilities caused by TPCs, and we still lack a comprehensive understanding of the security impact of TPC vulnerability against firmware. To fill in the knowledge gap, we design and implement , which leverages syntactical features and control-flow graph features to detect the TPCs in firmware, and then recognizes the corresponding vulnerabilities. Based on , we present the first l
