Advisory: KDE Security Advisory

Description: A vulnerability was reported in KDE kpdf. A remote user can cause arbitrary code to be executed on the target user's system.
A remote user can create a PDF file with a specially crafted catalog dictionary or a specially crafted Pages attribute that, when
loaded by the target user, will cause the viewer to enter an infinite loop.
The vulnerability resides in xpdf code (which is
shared by kpdf).
The underlying vulnerability in xpdf was reported by LMH.
|
Impact: A remote user can create a file that, when loaded by the target user, will cause the kpdf viewer on the target user's system to be disrupted.
|
Solution: The vendor has issued a fixed version (3.5.6).

CVE-2007-0104
1. Systems affected:
KDE 3.2.0 up to including KDE 3.5.5. KDE 3.5.6 and newer is
not affected. KOffice 1.2 and newer contain the same code.
2. Overview:
kpdf, the KDE pdf viewer, shares code with xpdf. xpdf contains
a vulnerability that can cause denial of service (infinite loop)
via a PDF file that contains a crafted catalog dictionary
or a crafted Pages attribute that references an invalid page
tree node.
3. Impact:
Remotely supplied pdf files can be used to disrupt the kpdf
viewer on the client machine.
4. Solution:
Source code patches have been made available which fix these
vulnerabilities. Contact your OS vendor / binary package provider
for information about how to obtain updated binary packages.
