This update for sudo fixes the following issues:
Fix two security vulnerabilities that allowed users to bypass sudo's NOEXEC functionality:
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. [bsc#1008043]
