Original Release Date: 2006-03-10

CVE-2006-0746

1. Systems affected:

KDE 3.3.2 with patch from CVE-2005-3627 applied. Please
note that the patch for KDE 3.4.x and newer was correct and
is unaffected.

2. Overview:

kpdf, the KDE pdf viewer, shares code with xpdf. xpdf contains
multiple vulnerabilities, one of them being CVE-2005-3627,
that was patched in the KDE security advisory 20051207-2.
However, the patch published for KDE 3.3.x was faulty and
only partially fixed the vulnerability. We'd like to thank
Marcelo Ricardo Leitner for bringing this error to our attention.
The Common Vulnerabilities and Exposures project has assigned
CVE-2006-0746 to this issue.

3. Impact:

Remotely supplied pdf files can be used to execute arbitrary
code 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.

5. Patch:

Patch for KDE 3.3.2 and newer is available from
ftp://ftp.kde.org/pub/kde/security_patches :
