PDFjam: Multiple vulnerabilities — GLSA 200903-05

Multiple vulnerabilities in the PDFjam scripts allow for local privilege escalation.

Affected Packages

app-text/pdfjam on all architectures
Affected versions < 1.20-r1
Unaffected versions >= 1.20-r1

Background

PDFjam is a small collection of shell scripts to edit PDF documents, including pdfnup, pdfjoin and pdf90.

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"
