On this Wednesday, Google released an update to its Chrome web browser and addresses five vulnerabilities in the application: one of them rated Critical and four others at High-risk.

The Chrome 57.0.2987.133 was released for Mac, Windows, and Linux users just a few weeks after the version 57 of browser made it to the market. In addition to bringing these functionality improvements, the previous browser release included the CSS Grid Layout availability, along with patches for almost 36 vulnerabilities.

The critical level bug resolved in this new update is after free vulnerability in the printing. Tracked as CVE-2017-5055, this issue was discovered by Wadih Matar, who got a $9,337 bounty for the finding, according to the Google’s advisory.

Coming to rest, first of the four High-risk flaws fixed in this release is a Heap buffer overflow in V8, discovered by Nicolas Trippar from Zimperium zLabs and was awarded a $3000 bounty. Another was a Bad cast in Blink, found by JeongHoon Shin and was awarded $1000.

The later two flaws included a Use after free in the Blink (CVE-2017-5056), discovered by a researcher who choose to remain anonymous, and an Out of bounds memory access in the V8 (CVE-2017-5053), found by the Team Sniper (Keen Lab and PC Mgr) and reported through the ZDI (ZDI-CAN-4587). Google did not reveal the bounties paid for these last two issues.

A new version of the Chrome for Android (57.0.2987.132) is now available this week to address a High-risk Use after a free vulnerability in Blink (CVE-2017-5056).

In late January, Google released Chrome 56 in the stable channel to resolve 51 vulnerabilities in the browser. Roughly two weeks later, the Internet giant announced that Gmail was dropping support for Chrome version 53 and below, hitting Windows XP and Vista users hard (Chrome 49 was the last browser iteration released for these platforms).
