Synopsis

========

 

Multiple integer overflows in the Ghostscript ICC library might allow

for user-assisted execution of arbitrary code.

 

Background

==========

 

Ghostscript is an interpreter for the PostScript language and the

Portable Document Format (PDF).

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 app-text/ghostscript-gpl < 8.64-r2 >= 8.64-r2

2 app-text/ghostscript-gnu < 8.62.0 >= 8.62.0

3 app-text/ghostscript-esp <= 8.15.4-r1 Vulnerable!

-------------------------------------------------------------------

NOTE: Certain packages are still vulnerable. Users should migrate

to another package if one is available or wait for the

existing packages to be marked stable by their

architecture maintainers.

-------------------------------------------------------------------

3 affected packages on all of their supported architectures.

-------------------------------------------------------------------

 

Description

===========

 

Jan Lieskovsky from the Red Hat Security Response Team discovered the

following vulnerabilities in Ghostscript's ICC Library:

 

* Multiple integer overflows (CVE-2009-0583).

 

* Multiple insufficient bounds checks on certain variable sizes

(CVE-2009-0584).

 

Impact

======

 

A remote attacker could entice a user to open a specially crafted

PostScript file containing images and a malicious ICC profile, possibly

resulting in the execution of arbitrary code with the privileges of the

user running the application.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All GPL Ghostscript users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=app-text/ghostscript-gpl-8.64-r2"

 

All GNU Ghostscript users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=app-text/ghostscript-gnu-8.62.0"

 

We recommend that users unmerge ESP Ghostscript and use GPL or GNU

Ghostscript instead:

 

# emerge --unmerge "app-text/ghostscript-esp"

 

For installation instructions, see above.
