3. Description:

 

The sudo packages contain the sudo utility which allows system

administrators to provide certain users with the permission to execute

privileged commands, which are used for system management purposes, without

having to log in as root.

 

Security Fix(es):

 

* It was discovered that the sudo noexec restriction could have been

bypassed if application run via sudo executed system(), popen(), or

wordexp() C library functions with a user supplied argument. A local user

permitted to run such application via sudo with noexec restriction could

use these flaws to execute arbitrary commands with elevated privileges.

(CVE-2016-7032, CVE-2016-7076)

 

These issues were discovered by Florian Weimer (Red Hat).
