The KDE kfile-info JPEG plugin provides meta-information about JPEG files.
Marcus Meissner of the SUSE security team discovered a stack overflow vulnerability in the code processing EXIF information in the kfile JPEG info plugin.
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.
There is no known workaround at this time.
All KDE users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-kfile-plugins-3.5.5-r1"
