"In GOsa², an LDAP web-frontend written in PHP, a vulnerability
was found that could theoretically have lead to unauthorized access to
the LDAP database managed with FusionDirectory. LDAP queries' result
status ('Success') checks had not been strict enough. The resulting
output containing the word 'Success' anywhere in the returned data
during login connection attempts would have returned 'LDAP success' to
FusionDirectory and possibly grant unwanted access.

For Debian 8 'Jessie', this problem has been fixed in version
2.7.4+reloaded2-1+deb8u4.

We recommend that you upgrade your gosa packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
