Synopsis

========

 

Multiple vulnerabilities in the PDFjam scripts allow for local

privilege escalation.

 

Background

==========

 

PDFjam is a small collection of shell scripts to edit PDF documents,

including pdfnup, pdfjoin and pdf90.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 app-text/pdfjam < 1.20-r1 >= 1.20-r1

 

Description

===========

 

* Martin Vaeth reported multiple untrusted search path

vulnerabilities (CVE-2008-5843).

 

* Marcus Meissner of the SUSE Security Team reported that temporary

files are created with a predictable name (CVE-2008-5743).

 

Impact

======

 

A local attacker could place a specially crafted Python module in the

current working directory or the /var/tmp directory, and entice a user

to run the PDFjam scripts, leading to the execution of arbitrary code

with the privileges of the user running the application. A local

attacker could also leverage symlink attacks to overwrite arbitrary

files.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All PDFjam users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=app-text/pdfjam-1.20-r1"
