Arch Linux Security Advisory ASA-201712-1
Date : 2017-12-02
CVE-ID : CVE-2017-14746 CVE-2017-15275
Package : samba
Type : multiple issues
Remote : Yes
Link : https://security.archlinux.org/AVG-535
The package samba before version 4.7.3-1 is vulnerable to multiple
issues including arbitrary code execution and information disclosure.
Upgrade to 4.7.3-1.
# pacman -Syu "samba>=4.7.3-1"
The problems have been fixed upstream in version 4.7.3.
It is possible to work around CVE-2017-14746 by disabling the SMB1
protocol in the [global] section in smb.conf:
server min protocol = SMB2
- CVE-2017-14746 (arbitrary code execution)
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
- CVE-2017-15275 (information 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.
A remote attacker is able to disclose sensitive information and execute
arbitrary code on the affected host.
