Gentoo Security Advisory GLSA 200404-01 (Portage)

Summary
The remote host is missing updates announced in advisory GLSA 200404-01.
Solution
Users should upgrade to Portage 2.0.50-r3 or later: # emerge sync # emerge -pv '>=sys-apps/portage-2.0.50-r3' # emerge '>=sys-apps/portage-2.0.50-r3' http://www.securityspace.com/smysecure/catid.html?in=GLSA%20200404-01 http://bugs.gentoo.org/show_bug.cgi?id=21923
Insight
A flaw has been found in the temporary file handling algorithms for the sandboxing code used within Portage. Lockfiles created during normal Portage operation of portage could be manipulated by local users resulting in the truncation of hard linked files causing a Denial of Service attack on the system.
