attacks
Date: November 10, 2017
Bugs: #634436, #634438
ID: 201711-03

Synopsis
=======
A flaw was discovered in the 4-way handshake in hostapd and
wpa_supplicant that allows attackers to conduct a Man in the Middle
attack.

Background
=========
wpa_supplicant is a WPA Supplicant with support for WPA and WPA2 (IEEE
802.11i / RSN). hostapd is a user space daemon for access point and
authentication servers.

Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-wireless/hostapd < 2.6-r1 >= 2.6-r1
2 net-wireless/wpa_supplicant
< 2.6-r3 >= 2.6-r3
-------------------------------------------------------------------
2 affected packages

Description
==========
WiFi Protected Access (WPA and WPA2) and it's associated technologies
are all vulnerable to the KRACK attacks. Please review the referenced
CVE identifiers for details.

Impact
=====
An attacker can carry out the KRACK attacks on a wireless network in
order to gain access to network clients. Once achieved, the attacker
can potentially harvest confidential information (e.g. HTTP/HTTPS),
inject malware, or perform a myriad of other attacks.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All hostapd users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-wireless/hostapd-2.6-r1"

All wpa_supplicant users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot -v ">=net-wireless/wpa_supplicant-2.6-r3"

Synopsis
=======
A vulnerability was discovered in MariaDB and MySQL which may allow
local users to gain root privileges.

Background
=========
MySQL is a popular multi-threaded, multi-user SQL server. MariaDB is an
enhanced, drop-in replacement for MySQL.

Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-db/mariadb < 10.0.30-r1 >= 10.0.30-r1
2 dev-db/mysql < 5.6.36-r1 >= 5.6.36-r1
-------------------------------------------------------------------
2 affected packages

Description
==========
The Gentoo installation scripts before 2017-09-29 have chown calls for
user-writable directory trees, which allows local users to gain
privileges by leveraging access to the mysql account for creation of a
link.

Impact
=====
A local attacker could escalate privileges to root.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All MariaDB users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">Þv-db/mariadb-10.0.30-r1"

All MySQL users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">Þv-db/mysql-5.6.36-r1"
