- Fix two security vulnerabilities that allowed users to bypass
 sudo's NOEXEC functionality:
 * noexec bypass via system() and popen() [CVE-2016-7032, bsc#1007766]
 * noexec bypass via wordexp() [CVE-2016-7076, bsc#1007501]

- The SSSD plugin would occasionally crash sudo with an 'internal error'.
 This issue has been fixed. [bsc#948973]

- The SSSD plugin would occasionally apply @netgroups rules from LDAP to all
 users rather than the @netgroup. This issue is now fixed. [bsc#966755]

- When the SSSD plugin was used and a local user ran sudo, an e-mail used to be
 sent to administrator because SSSD did not support sudo rules for local
 users. This message did not signify an error, however, it was only noise.
