Severity: Normal Title: eix: Insecure temporary file creation Date: November 22, 2005 Bugs: #112061 ID: 200511-19

Synopsis ========
eix has an insecure temporary file creation vulnerability, potentially allowing a local user to overwrite arbitrary files.
Background ==========
eix is a small utility for searching ebuilds with indexing for fast results.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-portage/eix < 0.5.0_pre2 >= 0.5.0_pre2 *>= 0.3.0-r2
Description ===========
Eric Romang discovered that eix creates a temporary file with a predictable name. eix creates a temporary file in /tmp/eix.*.sync where * is the process ID of the shell running eix.
Impact ======
A local attacker can watch the process list and determine the process ID of the shell running eix while the "emerge --sync" command is running, then create a link from the corresponding temporary file to a system file, which would result in the file being overwritten with the rights of the user running the application.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All eix users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose app-portage/eix
Availability ============
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
http://security.gentoo.org/glsa/glsa-200511-19.xml
