Vulnerability Scan Summary
eix: Insecure temporary file creation
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200511-19
(eix: Insecure temporary file creation)
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.
A local attacker can watch the process list and acertain 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.
There is no known workaround at this time.
All eix users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose app-portage/eix
Threat Level: Medium
