(Debian Issues Fix) Xpdf Integer Overflows in indexHigh and pageSize May Let Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1012052
SecurityTracker URL:  http://securitytracker.com/id/1012052
CVE Reference:   CVE-2004-0888, CVE-2004-0889, CVE-2005-0206   (Links to External Site)
Date:  Nov 3 2004
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 3.00
Description:   Some integer overflows were reported in Xpdf. A remote user may be able to execute arbitrary code on a target user's system.

Several vendors reported that there are integer overflows in Xpdf. A remote user can create a specially crafted PDF file that, when viewed by the target user, may execute arbitrary code.

The flaws reside in 'pdftops/Catalog.cc' and 'pdftops/XRef.cc'. A specially crafted Index color size (indexHigh) or Page size can trigger the overflow.

Chris Evans is credited with discovering these flaws.

CUPS, the Common UNIX Printing System, is also affected because it includes Xpdf.

Impact:   A remote user may be able to execute arbitrary code on a target user's system when the target user loads a malformed PDF file.
Solution:   Debian has released a fix for the stable distribution (woody) in version 1.00-3.2 and for the unstable distribution (sid) in version 3.00-9.

Debian GNU/Linux 3.0 alias woody:

Package        : xpdf
Vulnerability  : integer overflows
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-0888
Debian Bug     : 278298

Chris Evans discovered several integer overflows in xpdf, a viewer for
PDF files, which can be exploited remotely by a specially crafted PDF
document and lead to the execution of arbitrary code.

For the stable distribution (woody) these problems have been fixed in
version 1.00-3.2.

For the unstable distribution (sid) these problems have been fixed in
version 3.00-9.

We recommend that you upgrade your xpdf package.
