Synopsis
========
OpenLDAP and Gauche suffer from RUNPATH issues that may allow users in
the "portage" group to escalate privileges.
Background
==========
OpenLDAP is a suite of LDAP-related application and development tools.
Gauche is an R5RS Scheme interpreter.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-nds/openldap < 2.2.28-r3 >= 2.2.28-r3
*>= 2.1.30-r6
2 dev-lang/gauche < 0.8.6-r1 >= 0.8.6-r1
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
Gentoo packaging for OpenLDAP and Gauche may introduce insecure paths
into the list of directories that are searched for libraries at
runtime.
Impact
======
A local attacker, who is a member of the "portage" group, could create
a malicious shared object in the Portage temporary build directory that
would be loaded at runtime by a dependent binary, potentially resulting
in privilege escalation.
Workaround
==========
Only grant "portage" group rights to trusted users.
Resolution
==========
All OpenLDAP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose net-nds/openldap
All Gauche users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/gauche-0.8.6-r1"
