Busybox, utility programs for small and embedded systems, was affected by several security vulnerabilities. The Common Vulnerabilities and Exposures project identifies the following issues.

CVE-2011-5325

A path traversal vulnerability was found in Busybox implementation of tar. tar will extract a symlink that points outside of the current working directory and then follow that symlink when extracting other files. This allows for a directory traversal attack when extracting untrusted tarballs.

CVE-2013-1813

When device node or symlink in /dev should be created inside 2-or-deeper subdirectory (/dev/dir1/dir2.../node), the intermediate directories are created with incorrect permissions.

CVE-2014-4607

An integer overflow may occur when processing any variant of a 'literal run' in the lzo1x_decompress_safe function. Each of these three locations is subject to an integer overflow when processing zero bytes. This exposes the code that copies literals to memory corruption.

CVE-2014-9645

The add_probe function in modutils/modprobe.c in BusyBox allows local users to bypass intended restrictions on loading kernel modules via a / (slash) character in a module name, as demonstrated by an 'ifconfig /usbserial up' command or a 'mount -t /snd_pcm none /' command.

CVE-2016-2147

Integer overflow in the DHCP client (udhcpc) in BusyBox allows remote attackers to cause a denial of service (crash) via a malformed RFC1035-encoded domain name, which triggers an out-of-bounds heap write.

CVE-2016-2148

Heap-based buffer overflow in the DHCP client (udhcpc) in BusyBox allows remote attackers to have unspecified impact via vectors involving OPTION_6RD parsing.

CVE-2017-15873

The get_next_block function in archival/libarchive /decompress_bunzip2.c in BusyBox has an Integer Overflow that may lead to a write access violation.

CVE-2017-16544

In the add_match function in libbb/lineedit.c in BusyBox, the tab autocomplete feature of the shell, used to get a list of filenames in a directory, does not sanitize filenames and results in executing any escape sequence in the terminal. This could potentially result in code execution, arbitrary file writes, or other attacks.

CVE-2018-1000517

BusyBox contains a Buffer Overflow vulnerability in Busybox wget that can result in a heap-based buffer overflow. This attack appears to be exploitable via network connectivity.

CVE-2015-9621

Unziping a specially crafted zip file results in a computation of an invalid pointer and a crash reading an invalid address.

For Debian 9 stretch, these problems have been fixed in version 1:1.22.0-19+deb9u1.

We recommend that you upgrade your busybox packages.
