KDE kfile JPEG info plugin: Denial of service

Background

The KDE kfile-info JPEG plugin provides meta-information about JPEG files.

Description

Marcus Meissner of the SUSE security team discovered a stack overflow vulnerability in the code processing EXIF information in the kfile JPEG info plugin.

Impact

A remote attacker could entice a user to view a specially crafted JPEG image with a KDE application like Konqueror or digiKam, leading to a Denial of Service by an infinite recursion.

Workaround

There is no known workaround at this time.

Resolution

All KDE users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-kfile-plugins-3.5.5-r1"
