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 < 1.8g-r1 >= 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 ">=app-text/pstotext-1.8g-r1"
References
==========
