Background ========== OpenLDAP Software is an open source implementation of the Lightweight Directory Access Protocol. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-nds/openldap < 2.3.43 >= 2.3.43 Description =========== Cameron Hotchkies discovered an error within the parsing of ASN.1 BER encoded packets in the "ber_get_next()" function in libraries/liblber/io.c. Impact ====== A remote unauthenticated attacker can send a specially crafted ASN.1 BER encoded packet which will trigger the error and cause an "assert()", terminating the "slapd" daemon. Workaround ========== There is no known workaround at this time. Resolution ========== All OpenLDAP users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-nds/openldap-2.3.43" References ========== [ 1 ] CVE-2008-2952 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2952 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200808-09.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.
