Package : libmtp
Version : 1.1.8-1+deb8u1
CVE ID : CVE-2017-9831 CVE-2017-9832
libmtp is a library for communicating with MTP aware devices. The Media
Transfer Protocol (commonly referred to as MTP) is a devised set of custom
extensions to support the transfer of music files on USB digital audio players
and movie files on USB portable media players.
An integer overflow vulnerability in the ptp_unpack_EOS_CustomFuncEx
function of the ptp-pack.c file 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.
An integer overflow vulnerability in ptp-pack.c (ptp_unpack_OPL function)
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 8 "Jessie", these problems have been fixed in version
We recommend that you upgrade your libmtp packages.
