http://security.gentoo.org/

Severity:	normal
Title:	PDFjam: Multiple vulnerabilities
Date:	03/07/2009
Bugs:	#252734
ID:	200903-05

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	Architecture(s)
app-text/pdfjam	< 1.20-r1	>= 1.20-r1	All supported architectures

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"
