Synopsis

Important: chromium-browser security update

Type/Severity

Security Advisory: Important

Topic

An update for chromium-browser is now available for Red Hat Enterprise Linux 6 Supplementary.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

Chromium is an open-source web browser, powered by WebKit (Blink).

This update upgrades Chromium to version 64.0.3282.119.

Security Fix(es):

  • Multiple flaws were found in the processing of malformed web content. A web page containing malicious content could cause Chromium to crash, execute arbitrary code, or disclose sensitive information when visited by the victim. (CVE-2018-6031, CVE-2018-6032, CVE-2018-6033, CVE-2018-6034, CVE-2018-6035, CVE-2018-6036, CVE-2018-6037, CVE-2018-6038, CVE-2018-6039, CVE-2018-6040, CVE-2018-6041, CVE-2018-6042, CVE-2018-6043, CVE-2018-6045, CVE-2018-6046, CVE-2018-6047, CVE-2018-6048, CVE-2018-6049, CVE-2018-6050, CVE-2018-6051, CVE-2018-6052, CVE-2018-6053, CVE-2018-6054)
  • To mitigate timing-based side-channel attacks similar to "Spectre" and "Meltdown", this update reduces the precision of the timing data provided by the Date object and the performance.now() API, and the V8 JavaScript engine now uses masking of certain addresses and array or string indices.

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

After installing the update, Chromium must be restarted for the changes to take effect.
