<title>PDFKit, ImageKits: Buffer overflow</title>
|
|
<synopsis>
|
|
PDFKit and ImageKits are vulnerable to an integer overflow and a stack
|
|
overflow allowing for the user-assisted execution of arbitrary code.

PDFKit is a framework for rendering of PDF content in GNUstep
|
|
applications. ImageKits is a collection of frameworks to support
|
|
imaging in GNUstep applications.

Maurycy Prodeus discovered an integer overflow vulnerability possibly
|
|
leading to a stack-based buffer overflow in the XPDF code which PDFKit
|
|
is based on. ImageKits also contains a copy of PDFKit.

<impact type="normal">
|
|
<p>
|
|
By enticing a user to view a specially crafted PDF file with a viewer
|
|
based on ImageKits or PDFKit such as Gentoo's ViewPDF, a remote
|
|
attacker could cause an overflow, potentially resulting in the
|
|
execution of arbitrary code with the privileges of the user running the
|
|
application.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

PDFKit and ImageKits are not maintained upstream, so the packages were
|
|
masked in Portage. We recommend that users unmerge PDFKit and
|
|
ImageKits:
|
|
</p>
|
|
<code>
|
|
# emerge --unmerge gnustep-libs/pdfkit
|
|
# emerge --unmerge gnustep-libs/imagekits</code>
|
|
<p>
|
|
As an alternative, users should upgrade their systems to use PopplerKit
|
|
instead of PDFKit and Vindaloo instead of ViewPDF.
