GLSA-200710-20 : PDFKit, ImageKits: Buffer overflow

medium Nessus Plugin ID 27518

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200710-20 (PDFKit, ImageKits: Buffer overflow)

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 :

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.
Workaround :

There is no known workaround at this time.

Solution

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