Synopsis

GPdf, KPDF and KOffice all include vulnerable xpdf code to handle PDF files, making them vulnerable to execution of arbitrary code upon viewing a malicious PDF file.

2. Impact Information

Background

GPdf is a Gnome-based PDF viewer. KPDF, part of the kdegraphics package, is a KDE-based PDF viewer. KOffice is an integrated office suite for KDE.

Description

GPdf, KPDF and KOffice all include xpdf code to handle PDF files. xpdf is vulnerable to multiple integer overflows, as described in GLSA 200410-20.

Impact

An attacker could entice a user to open a specially-crafted PDF file, potentially resulting in execution of arbitrary code with the rights of the user running the affected utility.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All GPdf users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/gpdf-0.132-r2"

All KDE users should upgrade to the latest version of kdegraphics:

Code Listing 3.2: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.3.0-r2"

All KOffice users should upgrade to the latest version:

Code Listing 3.3: Resolution
