"libmtp, a library for communicating with MTP aware devices (like
cellular phones and audio players), was found to be vulnerable to
several integer overflow vulnerabilities, which allowed malicious
devices to cause denial of service crashes and maybe remote code
execution.

CVE-2017-9831

An integer overflow vulnerability in the ptp_unpack_EOS_CustomFuncEx
function of the ptp-pack.c file of libmtp (version 1.1.12 and below)
allows attackers to cause a denial of service (out-of-bounds memory
access) or maybe remote code execution by inserting a mobile device
into a personal computer through a USB cable.

CVE-2017-9832

An integer overflow vulnerability in ptp-pack.c (ptp_unpack_OPL
function) of libmtp (version 1.1.12 and below) allows attackers to
cause a denial of service (out-of-bounds memory access) or maybe
remote code execution by inserting a mobile device into a personal
computer through a USB cable.

For Debian 7 'Wheezy', these problems have been fixed in version
1.1.3-35-g0ece104-5+deb7u1.

We recommend that you upgrade your libmtp packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
