Synopsis
========
A vulnerability in Xpdf might allow local attackers to execute
arbitrary code.
Background
==========
Xpdf is a PDF file viewer that runs under the X Window System.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/xpdf < 3.02-r2 >= 3.02-r2
Description
===========
Erik Wallin reported that Gentoo's Xpdf attempts to read the "xpdfrc"
file from the current working directory if it cannot find a ".xpdfrc"
file in the user's home directory. This is caused by a missing
definition of the SYSTEM_XPDFRC macro when compiling a repackaged
version of Xpdf.
Impact
======
A local attacker could entice a user to run "xpdf" from a directory
containing a specially crafted "xpdfrc" file, resulting in the
execution of arbitrary code when attempting to, e.g., print a file.
Workaround
==========
Do not run Xpdf from untrusted working directories.
Resolution
==========
All Xpdf users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/xpdf-3.02-r2"
