Synopsis
=======

Multiple integer overflows were discovered in Xpdf, potentially resulting in execution of arbitrary code upon viewing a malicious PDF file. CUPS includes Xpdf code and therefore is vulnerable to the same issues.

Background
=========

Xpdf is an open source viewer for Portable Document Format (PDF) files. The Common UNIX Printing System (CUPS) is a cross-platform print spooler that includes some Xpdf code.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/xpdf <= 3.00-r2 >= 3.00-r3
2 net-print/cups <= 1.1.20-r3 >= 1.1.20-r4
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

Description
==========

Chris Evans discovered multiple integer overflow issues in Xpdf.

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. By enticing an user to directly print the PDF file to a CUPS printer, an attacker could also crash the CUPS spooler or execute arbitrary code with the rights of the CUPS spooler, which is usually the "lp" user.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All Xpdf users should upgrade to the latest version:

# emerge sync

# emerge -pv ">=app-text/xpdf-3.00-r3"
# emerge ">=app-text/xpdf-3.00-r3"

All CUPS users should also upgrade to the latest version:

# emerge sync

# emerge -pv ">=net-print/cups-1.1.20-r4"
# emerge ">=net-print/cups-1.1.20-r4"
