September 2016 by Vigil@nce
This bulletin was written by Vigil@nce : https://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can traverse directories via kf5-karchive of KDE
Frameworks, in order to create a file outside the service root
path.
Impacted products: Debian, Fedora, openSUSE, openSUSE Leap, SUSE
Linux Enterprise Desktop, SLES, Ubuntu.
Severity: 2/4.
Creation date: 25/07/2016.
DESCRIPTION OF THE VULNERABILITY
The KDE Frameworks product offers kf5-karchive to extract tar
archives.
However, user’s data are directly inserted in an access path.
Sequences such as "/.." can thus be used to go in the upper
directory.
An attacker can therefore traverse directories via kf5-karchive of
KDE Frameworks, in order to create a file outside the service root
path.
