[GLSA-200403-12] OpenLDAP DoS Vulnerability

Vulnerability Assessment Summary
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.

# emerge sync
