Gentoo Linux Security Advisory
Title: Ghostscript: Buffer overflow (GLSA 200803-14)
Severity: normal
Exploitable: remote
Date: March 08, 2008
Bug(s): #208999
ID: 200803-14
Synopsis
A stack-based buffer overflow has been discovered in Ghostscript, allowing arbitrary code execution.
Background
Ghostscript is a suite of software based on an interpreter for PostScript and PDF.
Affected Packages
Package: app-text/ghostscript-esp
Vulnerable: < 8.15.4-r1
Unaffected: >= 8.15.4-r1
Architectures: All supported architectures
Package: app-text/ghostscript-gpl
Vulnerable: < 8.61-r3
Unaffected: >= 8.61-r3
Architectures: All supported architectures
Package: app-text/ghostscript-gnu
Vulnerable: < 8.60.0-r2
Unaffected: >= 8.60.0-r2
Architectures: All supported architectures
Description
Chris Evans (Google Security) discovered a stack-based buffer overflow within the zseticcspace() function in the file zicc.c when processing a PostScript file containing a long "Range" array in a .seticcscpate operator.
Impact
A remote attacker could exploit this vulnerability by enticing a user to open a specially crafted PostScript file, which could possibly lead to the execution of arbitrary code or a Denial of Service.
Workaround
There is no known workaround at this time.
Resolution
All Ghostscript ESP users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/ghostscript-esp-8.15.4-r1" | All Ghostscript GPL users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/ghostscript-gpl-8.61-r3" | All Ghostscript GNU users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/ghostscript-gnu-8.60.0-r2" |
