/usr/libexec/openldap/generate-server-cert.sh in openldap-servers sets weak permissions for the TLS certificate, which allows local users to obtain the TLS certificate by leveraging a race condition between the creation of the certificate, and the chmod to protect it.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - openldap: ACL restrictions bypass due to sasl_ssf value being set permanently (CVE-2019-13565)

  - /usr/libexec/openldap/generate-server-cert.sh in openldap-servers sets weak permissions for the TLS     certificate, which allows local users to obtain the TLS certificate by leveraging a race condition between     the creation of the certificate, and the chmod to protect it. (CVE-2016-4984)

  - An issue was discovered in the server in OpenLDAP before 2.4.48. When the server administrator delegates     rootDN (database admin) privileges for certain databases but wants to maintain isolation (e.g., for multi-     tenant deployments), slapd does not properly stop a rootDN from requesting authorization as an identity     from another database during a SASL bind or with a proxyAuthz (RFC 4370) control. (It is not a common     configuration to deploy a system where the server administrator and a DB administrator enjoy different     levels of trust.) (CVE-2019-13057)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - openldap: incorrect multi-keyword mode cipherstring parsing (CVE-2015-3276)

  - /usr/libexec/openldap/generate-server-cert.sh in openldap-servers sets weak permissions for the TLS     certificate, which allows local users to obtain the TLS certificate by leveraging a race condition between     the creation of the certificate, and the chmod to protect it. (CVE-2016-4984)

  - servers/slapd/back-mdb/search.c in OpenLDAP through 2.4.44 is prone to a double free vulnerability. A user     with access to search the directory can crash slapd by issuing a search including the Paged Results     control with a page size of 0. (CVE-2017-9287)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - openldap-servers: /usr/libexec/openldap/generate-server-cert.sh create world readable password file     (CVE-2016-4984)

  - An off-by-one error leading to a crash was discovered in openldap 2.4 when processing DNS SRV messages. If     slapd was configured to use the dnssrv backend, an attacker could crash the service with crafted DNS     responses. (CVE-2014-8182)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
