Xpdf, GPdf: New integer overflows — GLSA 200412-24

New integer overflows were discovered in Xpdf, potentially resulting in the execution of arbitrary code. GPdf includes Xpdf code and therefore is vulnerable to the same issues.

Affected Packages

app-text/xpdf on all architectures
Affected versions <= 3.00-r6
Unaffected versions >= 3.00-r7
app-text/gpdf on all architectures
Affected versions <= 2.8.1
Unaffected versions >= 2.8.1-r1

Background

Xpdf is an open source viewer for Portable Document Format (PDF) files. GPdf is a Gnome-based PDF viewer that includes some Xpdf code.

Description

A new integer overflow issue was discovered in Xpdf's Gfx::doImage() function.

Impact

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

Workaround

There is no known workaround at this time.

Resolution

All Xpdf users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.00-r7"

All GPdf users should also upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-text/gpdf-2.8.1-r1"
