Xpdf, Kpdf and GPdf may crash as a result of a Denial of Service vulnerability.

2.  Impact Information


Xpdf, Kpdf and GPdf are PDF file viewers that run under the X Window System. Kpdf and GPdf both contain Xpdf code. Kpdf is also part of kdegraphics.


Xpdf, Kpdf and GPdf do not handle a broken table of embedded TrueType fonts correctly. After detecting such a table, Xpdf, Kpdf and GPdf attempt to reconstruct the information in it by decoding the PDF file, which causes the generation of a huge temporary file.


A remote attacker may cause a Denial of Service by creating a specially crafted PDF file, sending it to a CUPS printing system (which uses Xpdf), or by enticing a user to open it in Xpdf, Kpdf, or GPdf.

3.  Resolution Information


There is no known workaround at this time.


All Xpdf users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/xpdf-3.00-r10"

All GPdf users should upgrade to the latest version:

Code Listing 3.2: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/gpdf-2.10.0-r1"

All Kpdf users should upgrade to the latest version:

Code Listing 3.3: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.3.2-r3"

All KDE Split Ebuild Kpdf users should upgrade to the latest version:

Code Listing 3.4: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/kpdf-3.4.1-r1"
