Gentoo Linux Security Advisory GLSA 200711-33
https://security.gentoo.org/
Severity: Low
Title: nss_ldap: Information disclosure
Date: November 25, 2007
Bugs: #198390
ID: 200711-33
Synopsis
=======
A race condition might lead to theft of user credentials or information
disclosure in services using nss_ldap.
Background
=========
nss_ldap is a Name Service Switch module which allows 'passwd', 'group'
and 'host' database information to be pulled from LDAP.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-auth/nss_ldap < 258 >= 258
==========
Josh Burley reported that nss_ldap does not properly handle the LDAP
connections due to a race condition that can be triggered by
multi-threaded applications using nss_ldap, which might lead to
requested data being returned to a wrong process.
Impact
=====
Remote attackers could exploit this race condition by sending queries
to a vulnerable server using nss_ldap, possibly leading to theft of
user credentials or information disclosure (e.g. Dovecot returning
wrong mailbox contents).
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All nss_ldap users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-auth/nss_ldap-258"
