KDE PS/PDF handling vulnerability
------------------------------------------------------------------------
SUMMARY
KDE uses Ghostscript for processing of PostScript (PS) and PDF files in a
way that allows for the execution of arbitrary commands that can be
contained in such files.
DETAILS
An attacker can prepare a malicious PostScript or PDF file which will
provide the attacker with access to the victim's account and privileges
when the victim opens this malicious file for viewing or when the victim
browses a directory containing such malicious file and has file previews
enabled.
An attacker can provide malicious files remotely to a victim in an e-mail,
as part of a webpage, via an ftp server and possible other means.
The vulnerabilities potentially enable local or remote attackers to
compromise the privacy of a vicitim's data and to execute arbitrary shell
commands with the victim's privileges, such as erasing files or accessing
or modifying data.
Effected versions:
All KDE 2 and KDE 3 versions up to and including KDE 3.1.1.
Solution:
The affected applications have been fixed in KDE 3.0.5b and KDE 3.1.1a,
both released today. We strongly recommend upgrading to these releases.
Upgrading KDEGraphics package and associated to stable version 2.2.2-6.11
also fixes the problem.
