Gentoo: GLSA-200903-37: Ghostscript: User-assisted execution of arbitrary code
Summary
Gentoo Linux Security Advisory GLSA 200903-37
https://security.gentoo.org/
Severity: Normal
Title: Ghostscript: User-assisted execution of arbitrary code
Date: March 23, 2009
Bugs: #261087
ID: 200903-37
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.
-------------------------------------------------------------------
==========
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.
