An update that solves two vulnerabilities and has three security fixes can now be installed.

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]
