CVE-2020-27840

A flaw was found in samba. Spaces used in a string around a domain name (DN), while supposed to be ignored, can cause invalid DN strings with spaces to instead write a zero-byte into out-of-bounds memory, resulting in a crash. The highest threat from this vulnerability is to system availability.

This flaw does not affect the version of Samba shipped with Red Hat Enterprise Linux and Red Hat Gluster Storage 3 because there is no support for Samba as Active Directory Domain Controller.
