1) Input validation error

EUVDB-ID: #VU40781

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2015-1258

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

Google Chrome before 43.0.2357.65 relies on libvpx code that was not built with an appropriate --size-limit value, which allows remote attackers to trigger a negative value for a size field, and consequently cause a denial of service or possibly have unspecified other impact, via a crafted frame size in VP9 video data.

Mitigation

Install update from vendor's website.
