Red Hat Enterprise Linux 6 Supplementary update for chromium-browser

1) Improper access control

EUVDB-ID: #VU40288

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2016-1667

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The TreeScope::adoptIfNeeded function in WebKit/Source/core/dom/TreeScope.cpp in the DOM implementation in Blink, as used in Google Chrome before 50.0.2661.102, does not prevent script execution during node-adoption operations, which allows remote attackers to bypass the Same Origin Policy via a crafted web site.

Mitigation

Install updates from vendor's website.

2) Improper access control

EUVDB-ID: #VU40287

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2016-1668

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The forEachForBinding function in WebKit/Source/bindings/core/v8/Iterable.h in the V8 bindings in Blink, as used in Google Chrome before 50.0.2661.102, uses an improper creation context, which allows remote attackers to bypass the Same Origin Policy via a crafted web site.

Mitigation

Install updates from vendor's website.

Risk: Low

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-1669

CWE-ID: CWE-120 - Buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to buffer overflow in the zone.cc. A remote attacker can send specially crafted JavaScript code, trigger buffer overflow and cause the application to crash.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Install updates from vendor's website.

4) Race condition

EUVDB-ID: #VU40286

Risk: Medium

CVSSv4.0: 2.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2016-1670

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to manipulate data.

Race condition in the ResourceDispatcherHostImpl::BeginRequest function in content/browser/loader/resource_dispatcher_host_impl.cc in Google Chrome before 50.0.2661.102 allows remote attackers to make arbitrary HTTP requests by leveraging access to a renderer process and reusing a request ID.

Mitigation

Install updates from vendor's website.
