GPdf: heap overflows in included Xpdf code

Background

GPdf is a Gnome PDF viewer.

Description

Dirk Mueller found a heap overflow vulnerability in the XPdf codebase when handling splash images that exceed size of the associated bitmap.

Impact

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

Workaround

There is no known workaround at this time.

Resolution

All GPdf users should upgrade to the latest version.

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-text/gpdf-2.10.0-r4"
