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	Architecture(s)
sys-auth/sssd	< 2.5.2-r1	>= 2.5.2-r1	All supported architectures

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"
