SUSE SLES11 Security Update : sudo (SUSE-SU-2016:2891-1)

high Nessus Plugin ID 95312

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

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]

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
