Gentoo Linux Security Advisory
Title: Ghostscript: User-assisted execution of arbitrary code (GLSA 200903-37)
Severity: normal
Exploitable: remote
Date: March 23, 2009
Bug(s): #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: app-text/ghostscript-gpl
Vulnerable: < 8.64-r2
Unaffected: >= 8.64-r2
Architectures: All supported architectures
Package: app-text/ghostscript-gnu
Vulnerable: < 8.62.0
Unaffected: >= 8.62.0
Architectures: All supported architectures
Package: app-text/ghostscript-esp
Vulnerable: <= 8.15.4-r1
Architectures: All 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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/ghostscript-gpl-8.64-r2" | All GNU Ghostscript users should upgrade to the latest version: Code: | # 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: Code: | # emerge --unmerge "app-text/ghostscript-esp" | For installation instructions, see above.
