Amazon Linux 1 Security Advisory: ALAS-2014-294
Advisory Release Date: 2014-02-26 16:22 Pacific
Advisory Updated Date: 2014-09-16 22:33 Pacific
Severity:
Medium
Issue Overview:
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.
Affected Packages:
openldap
Issue Correction:
Run yum update openldap to update your system.
