Gentoo Linux Security Advisory GLSA 200904-07

                                        http://security.gentoo.org/

Severity: Normal
Title: Xpdf: Untrusted search path
Date: April 07, 2009
Bugs: #242930
ID: 200904-07

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 &quot;&gt;=app-text/xpdf-3.02-r2&quot;
