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 Description =========== 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" References ========== [ 1 ] CVE-2007-5794 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5794 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200711-33.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
