Severity:	low
Title:	OpenLDAP, Gauche: RUNPATH issues
Date:	12/15/2005
Bugs:	#105380, #112577
ID:	200512-07

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	Architecture(s)
net-nds/openldap	< 2.2.28-r3	>= 2.2.28-r3	All supported architectures
dev-scheme/gauche	< 0.8.6-r1	>= 0.8.6-r1	All 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-scheme/gauche-0.8.6-r1"
