Amazon Linux AMI Security Advisory: ALAS-2017-933
Advisory Release Date: 2017-12-21 22:58 Pacific
Severity: Important

Issue Overview:

Use-after-free in processing SMB1 requests
A use-after-free flaw was found in the way samba servers handled certain SMB1 requests. An unauthenticated attacker could send specially-crafted SMB1 requests to cause the server to crash or execute arbitrary code. (CVE-2017-14746 )

Server heap-memory disclosure
A memory disclosure flaw was found in samba. An attacker could retrieve parts of server memory, which could contain potentially sensitive data, by sending specially-crafted requests to the samba server. (CVE-2017-15275 )
