Synopsis
========

A vulnerability has been discovered in pip, which could lead to
arbitrary configuration options being injected.

Background
==========

pip is a tool for installing and managing Python packages.

Affected packages
=================

Package         Vulnerable    Unaffected
--------------  ------------  ------------
dev-python/pip  < 23.3        >= 23.3

Description
===========

Multiple vulnerabilities have been discovered in pip. Please review the
CVE identifiers referenced below for details.

Impact
======

When installing a package from a Mercurial VCS URL  (ie "pip install
hg+..."), the specified Mercurial revision could be used to inject
arbitrary configuration options to the "hg clone" call (ie "--config").
Controlling the Mercurial configuration can modify how and which
repository is installed. This vulnerability does not affect users who
aren't installing from Mercurial.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All pip users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-python/pip-23.3"
