New KDE 3.1.1a packages are available for Slackware 9.0 which fix a security problem with the handling of PS and PDF documents.
Here are the details from the Slackware 9.0 ChangeLog:
Thu Apr 17 15:32:15 PDT 2003 patches/packages/kde/*: Upgraded to KDE 3.1.1a. Also included in this directory are a rebuild of Qt (linked with Xft2 rather than Xft1), an updated aRts package (the aRts sound server is a component of KDE, but ships as part of Slackware's L series), and kdevelop-3.0a4a.
Note that this update addresses a security problem with KDE's handling of PostScript documents. This is the overview of the problem from the KDE site:
KDE uses Ghostscript software 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. 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.
We recommend that sites running KDE install this update.
Please note that the change from Xft1 to Xft2 has changed the available fonts in Konsole (and presumably elsewhere), and that Xft2 seems unable to display the Linux Console font that was previously Slackware's default. Also, it doesn't handle gamma correction when displaying fonts against a black background, so we've had to change the default to black fonts on a white background (this is Konsole's default). This creates an additional issue with certain file types displayed as bold white by /etc/DIR_COLORS becoming invisible in directory listings. A workaround is to comment out these lines (or change to a different color):
.mpg 01;37 > movie formats .avi 01;37 .mov 01;37
( Security fix )
