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.
|
|

<description>
|
|
<p>
|
|
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.
|
|
</p>
|
|
<p>
|
|
Such a crash is not guaranteed with every failed operation, however, it
|
|
is possible.
|
|

<impact type="normal">
|
|
<p>
|
|
An attacker (or indeed, a normal user) may crash the OpenLDAP server,
|
|
creating a Denial of Service condition.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
A workaround is not currently known for this issue. All users are
|
|
advised to upgrade to the latest version of the affected package.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
OpenLDAP users should upgrade to version 2.1.13 or later:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
|
|
# emerge -pv ">=net-nds/openldap-2.1.13"
|
|
# emerge ">=net-nds/openldap-2.1.13"</code>
|
|
</resolution>
