EUVDB-ID: #VU32142

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-2016-5153

CWE-ID: CWE-19 - Data Handling

Exploit availability: No

Description

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

The Web Animations implementation in Blink, as used in Google Chrome before 53.0.2785.89 on Windows and OS X and before 53.0.2785.92 on Linux, improperly relies on list iteration, which allows remote attackers to cause a denial of service (use-after-destruction) or possibly have unspecified other impact via a crafted web site.

Mitigation

Install update from vendor's website.
