Date:	01/12/2007
Bugs:	#155949
ID:	200701-05

Synopsis

The KDE kfile JPEG info plugin of kdegraphics could enter an endless loop leading to a Denial of Service.

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
kde-base/kdegraphics-kfile-plugins	< 3.5.5-r1	>= 3.5.5-r1	All supported architectures

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"
