Date:	09/22/2024
Bugs:	#905356
ID:	202409-01

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	Architecture(s)
sys-apps/portage	< 3.0.47	>= 3.0.47	All supported architectures

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"
