Google Chrome < 49.0.2623.75 Multiple Vulnerabilities

High

Synopsis

The remote host is utilizing a web browser that is affected by multiple vulnerabilities.

Description

The version of Google Chrome installed on the remote host is prior to 49.0.2623.75, and is affected by multiple vulnerabilities :

- Multiple overflow conditions exist in the libpng library in the 'png_set_PLTE()' and 'png_get_PLTE()' functions due to improper handling of bit depths less than eight. A remote attacker can exploit this, via a specially crafted PNG image, to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-8126) - An unspecified flaw exists in Blink that allows an attacker to bypass the same-origin policy. (CVE-2016-1630) - An unspecified flaw exists in the Pepper plugin that allows an attacker to bypass the same-origin policy. (CVE-2016-1631) - A bad cast flaw exists in the Extensions component that allows an attacker to have an unspecified impact. (CVE-2016-1632) - Multiple use-after-free errors exist in Blink. A remote attacker can exploit these issues to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-1633, CVE-2016-1634, CVE-2016-1635) - An unspecified flaw exists that allows an attacker to bypass SRI validation. (CVE-2016-1636) - An unspecified flaw exists that allows an attacker to disclose sensitive information. (CVE-2016-1637) - An unspecified flaw exists that allows an attacker to bypass the webAPI. (CVE-2016-1638) - A use-after-free error exists in WebRTC. A remote attacker can exploit this issue to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-1639) - An unspecified origin confusion flaw exists in the Extensions UI that allows an attacker to have an unspecified impact. (CVE-2016-1640) - A use-after-free error exists in Favicon. A remote attacker can exploit this issue to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-1641) - Multiple flaws exist that allow a remote attacker to execute arbitrary code. (CVE-2016-1642) - Multiple unspecified flaws exist in Google V8 in 'runetime-scopes.cc' that allows an attacker to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-2843) - A bad cast flaw in 'layout/LayoutBlock.cpp' that is triggered as anonymous block wrappers are not properly removed from inline children allowing a context-dependent attacker to execute arbitrary code. (CVE-2016-2844) - A flaw that is triggered as the path component of the URL is not properly validated when handling a response fetched via ServiceWoker. (CVE-2016-2845)

Solution

Update the Chrome browser to 49.0.2623.75 or later.
