Cross-References:   CVE-2016-7032 CVE-2016-7076
Affected Products:
                    SUSE Linux Enterprise Server 11-SP4
                    SUSE Linux Enterprise Debuginfo 11-SP4
______________________________________________________________________________

   An update that solves two vulnerabilities and has three
   fixes is now available.

Description:


   This update for sudo fixes the following issues:

   - 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. [bsc#1008043]
