Right, my bad, a leftover of an import I dismissed. Do you want me to
reupload the patch?

Title:
  [SRU] denial of service via an LDAP search query (CVE-2012-1164,
  CVE-2013-4449, CVE-2015-1545)

Status in openldap package in Ubuntu:
  Fix Released
Status in openldap source package in Precise:
  Triaged
Status in openldap package in Debian:
  Fix Released

Bug description:
  [Impact]

  * CVE-2012-1164:
    - slapd in OpenLDAP before 2.4.30 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via an LDAP search query with attrsOnly set to true, which causes empty attributes to be returned.
    - Trusty ships 2.4.31 which comes with a fix for this.

  * CVE-2013-4449
    - The rwm overlay in OpenLDAP 2.4.23, 2.4.36, and earlier does not properly count references, which allows remote attackers to cause a denial of service (slapd crash) by unbinding immediately after a search request, which triggers rwm_conn_destroy to free the session context while it is being used by rwm_op_search.
    - This bug affects all the series (precise, trusty, utopic, vivid and wily)

  * CVE-2015-1545
    - The deref_parseCtrl function in servers/slapd/overlays/deref.c in OpenLDAP 2.4.13 through 2.4.40 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via an empty attribute list in a deref control in a search request.
    - This bug affects all the series (precise, trusty, utopic, vivid and wily)

  [Regression Potential]

  * this set of patches adds validations to avoid segfaults, so no
  regression is expected.
