Summary

Open Source Samba Vulnerabilities

Vulnerability Details

CVEID: CVE-2017-12163
DESCRIPTION: Samba could allow a remote authenticated attacker to obtain
sensitive information, caused by a memory leak over SMB1. By sending specially
crafted SMB1 data, an attacker could exploit this vulnerability to cause
portions of server memory contents to be written to a file and obtain sensitive
information.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
132351 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID: CVE-2017-12151
DESCRIPTION: Samba could provide weaker than expected security, caused by the
failure to properly sign and encrypt DFS redirects when the max protocol for
the original connection is set as ''SMB3''. An attacker could exploit this
vulnerability using man-in-the-middle techniques to read and alter confidential
documents.
CVSS Base Score: 7.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
132350 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)

CVEID: CVE-2017-12150
DESCRIPTION: Samba could allow a remote attacker to obtain sensitive
information, caused by the failure to require SMB signing in SMB1/2/3
connections. An attacker could exploit this vulnerability using
man-in-the-middle techniques to hijack client connections and obtain sensitive
information.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
132349 for the current score
CVSS Environmental Score*: Undefined
