Subject: Helix Code Security Advisory - go-gnome pre-installer
From: Helix Code, Inc. (securityHELIXCODE.COM)

HELIX CODE, INC. SECURITY ADVISORY
securityhelixcode.com Issue Date: 29 Aug 2000

PACKAGES AFFECTED:
"go-gnome" Helix GNOME pre-installer

SYNOPSIS:
A vulnerability in the go-gnome pre-installer allows non-root users to exploit
world-writable permissions in /tmp, permitting files normally only accessible
by root to be overwritten.

DESCRIPTION:
The go-gnome pre-installer uses a few rather predictable filenames in /tmp
for uudecode, snarf, and the installer files. If one (or more) of those files
already exist with a symbolic link created by a malicious user, the files
pointed to by those links will be clobbered.

SOLUTION:
The go-gnome pre-installer has been updated on the main Helix Code mirror and
go-gnome.com. This new version fixes this vulnerability by storing files in
/var/cache/helix-install, which is writable only by root.

AVAILABILITY:
A new version of the go-gnome pre-installer is available immediately from Helix
Code, Inc. at go-gnome.com:

http://go-gnome.com
