Gentoo Linux Security Advisory

Title: PDFjam: Multiple vulnerabilities (GLSA 200903-05)
Severity: normal
Exploitable: local
Date: March 07, 2009
Bug(s): #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: app-text/pdfjam
Vulnerable: < 1.20-r1
Unaffected: >= 1.20-r1
Architectures: 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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/pdfjam-1.20-r1"
