GLSA-200403-12 : OpenLDAP DoS Vulnerability

medium Nessus Plugin ID 14463

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

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 :

 An attacker (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 the affected package.

Solution

OpenLDAP users should upgrade to version 2.1.13 or later:
 # emerge sync # emerge -pv '>=net-nds/openldap-2.1.13' # emerge '>=net-nds/openldap-2.1.13'
