Samba is an open-source implementation of the Server Message Block (SMB) or
Common Internet File System (CIFS) protocol, which allows PC-compatible
machines to share files, printers, and other information.
Security Fix(es):
* 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)
* 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)
Red Hat would like to thank the Samba project for reporting these issues.
