OpenLDAP DoS Vulnerability Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200403-12 (OpenLDAP DoS Vulnerability) A password extended operation (password EXOP) which fails will cause the slapd server to free() an uninitialized pointer, possibly resulting in a segfault. This only affects servers using the back-ldbm backend. Such a crash is not guaranteed with every failed operation, however, it is possible. Impact A possible hacker (or indeed, a normal user) may crash the OpenLDAP server, creating a Denial of Service condition. Workaround A workaround is not currently known for this issue. All users are advised to upgrade to the latest version of OpenLDAP. References: http://www.openldap.org/its/index.cgi?findid=2390 Solution: OpenLDAP users should upgrade to version 2.1.17 or later: # emerge sync # emerge -pv ">=net-nds/openldap-2.1.17" # emerge ">=net-nds/openldap-2.1.17" Network Security Threat Level: Medium Networks Security ID: Vulnerability Assessment Copyright: (C) 2005 Michel Arboi |
