Synopsis
========
A vulnerability has been discovered in Portage, where PGP signatures
would not be verified.
Background
==========
Portage is the default Gentoo package management system.
Affected packages
=================
Package Vulnerable Unaffected
---------------- ------------ ------------
sys-apps/portage < 3.0.47 >= 3.0.47
Description
===========
Multiple vulnerabilities have been discovered in Portage. Please review
the CVE identifiers referenced below for details.
Impact
======
When using the webrsync mechanism to sync the tree the PGP signatures
that protect the integrity of the data in the tree would not be
verified. This would allow a man-in-the-middle attack to inject
arbitrary content into the tree.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Portage users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/portage-3.0.47"
