Description

An update for firefox is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Critical. 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.

Mozilla Firefox is an open source web browser.

Security Fix(es) :

  • A flaw was found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2017-5428)

Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Chaitin Security Research Lab via Trend Micro's Zero Day Initiative as the original reporters.
