Synopsis
========

A vulnerability has been discovered in SSSD, which can lead to arbitrary
code execution.

Background
==========

SSSD provides a set of daemons to manage access to remote directories
and authentication mechanisms such as LDAP, Kerberos or FreeIPA. It
provides an NSS and PAM interface toward the system and a pluggable
backend system to connect to multiple different account sources.

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

Package        Vulnerable    Unaffected
-------------  ------------  ------------
sys-auth/sssd  < 2.5.2-r1    >= 2.5.2-r1

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

A vulnerability has been discovered in SSSD. Please review the CVE
identifier referenced below for details.

Impact
======

A flaw was found in SSSD, where the sssctl command was vulnerable to
shell command injection via the logs-fetch and cache-expire subcommands.
This flaw allows an attacker to trick the root user into running a
specially crafted sssctl command, such as via sudo, to gain root access.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All SSSD users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-auth/sssd-2.5.2-r1"
