CentOS Errata and Security Advisory CESA-2017:3382
Mozilla Firefox is an open source web browser.
This update upgrades Firefox to version 52.5.1 ESR.
Security Fix(es):
- A privacy flaw was discovered in Firefox. In Private Browsing mode, a web worker could write persistent data to IndexedDB, which was not cleared when exiting and would persist across multiple sessions. A malicious website could exploit the flaw to bypass private-browsing protections and uniquely fingerprint visitors. (CVE-2017-7843)
Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Konark as the original reporter.
