Summary
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gentoo Linux Security Advisory GLSA 200803-14 https://security.gentoo.org/
Severity: Normal Title: Ghostscript: Buffer overflow Date: March 08, 2008 Bugs: #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 / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/ghostscript-esp < 8.15.4-r1 >= 8.15.4-r1 2 app-text/ghostscript-gpl < 8.61-r3 >= 8.61-r3 3 app-text/ghostscript-gnu < 8.60.0-r2 >= 8.60.0-r2 ------------------------------------------------------------------- 3 affected packages on all of their supported architectures. -------------------------------------------------------------------
========== 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:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/ghostscript-esp-8.15.4-r1"
All Ghostscript GPL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/ghostscript-gpl-8.61-r3"
All Ghostscript GNU users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/ghostscript-gnu-8.60.0-r2"
