Scientific Linux Security Update : 389-ds-base on SL7.x x86_64

High Nessus Plugin ID 99349


The remote Scientific Linux host is missing one or more security updates.


Security Fix(es) :

- An invalid pointer dereference flaw was found in the way 389-ds-base handled LDAP bind requests. A remote unauthenticated attacker could use this flaw to make ns-slapd crash via a specially crafted LDAP bind request, resulting in denial of service. (CVE-2017-2668)

Bug Fix(es) :

- Previously, when adding a filtered role definition that uses the 'nsrole' virtual attribute in the filter, Directory Server terminated unexpectedly. A patch has been applied, and now the roles plug-in ignores all virtual attributes. As a result, an error message is logged when an invalid filter is used. Additionally, the role is deactivated and Directory Server no longer fails.

- In a replication topology, Directory Server incorrectly calculated the size of string format entries when a lot of entries were deleted. The calculated size of entries was smaller than the actual required size. Consequently, Directory Server allocated insufficient memory and terminated unexpectedly when the data was written to it.
With this update, the size of string format entries is now calculated correctly in the described situation and Directory Server no longer terminates unexpectedly.


Update the affected packages.
