GPdf includes vulnerable Xpdf code to handle PDF files, making it vulnerable to the execution of arbitrary code.

2.  Impact Information


GPdf is a Gnome PDF viewer.


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


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.

3.  Resolution Information


There is no known workaround at this time.


All GPdf users should upgrade to the latest version.

Code Listing 3.1: Resolution

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