Synopsis
=======
pstotext contains a vulnerability which can potentially result in the execution of arbitrary code.
Background
=========
pstotext is a program that works with GhostScript to extract plain text from PostScript and PDF files.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/pstotext lt; 1.8g-r1 gt;= 1.8g-r1
Description
==========
Max Vozeler reported that pstotext calls the GhostScript interpreter on untrusted PostScript files without specifying the -dSAFER option.
Impact
=====
An attacker could craft a malicious PostScript file and entice a user to run pstotext on it, resulting in the execution of arbitrary commands with the permissions of the user running pstotext.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All pstotext users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "gt;=app-text/pstotext-1.8g-r1"
