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"
