Samba CVE-2016-2123 Heap Based Buffer Overflow Vulnerability
Samba is prone to a heap-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it to an insufficiently sized memory buffer.
An attacker can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely result in a denial of service.
The following versions are vulnerable:
Samba 4.3.x prior to 4.3.13
Samba 4.4.x prior to 4.4.8
Samba 4.5.x prior to 4.5.3
