Synopsis ========
A failed password operation can cause the OpenLDAP slapd server, if it is using the back-ldbm backend, to free memory that was never allocated.
Background ==========
OpenLDAP is a suite of LDAP-related application and development tools. It includes slapd (the standalone LDAP server), slurpd (the standalone LDAP replication server), and various LDAP libraries, utilities and example clients.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- net-nds/openldap <= 2.1.12 >= 2.1.13
Description ===========
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.
Resolution ==========
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"
