USN-3918-1: Firefox vulnerabilities

21 March 2019

firefox vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  o Ubuntu 18.10
  o Ubuntu 18.04 LTS
  o Ubuntu 16.04 LTS

Summary

Several security issues were fixed in Firefox.

Software Description

  o firefox - Mozilla Open Source web browser

Details

Multiple security issues were discovered in Firefox. If a user were tricked in
to opening a specially crafted website, an attacker could potentially exploit
these to cause a denial of service via application crash, denial of service via
successive FTP authorization prompts or modal alerts, trick the user with
confusing permission request prompts, obtain sensitive information, conduct
social engineering attacks, or execute arbitrary code. (CVE-2019-9788,
CVE-2019-9789, CVE-2019-9790, CVE-2019-9791, CVE-2019-9792, CVE-2019-9795,
CVE-2019-9796, CVE-2019-9797, CVE-2019-9799, CVE-2019-9802, CVE-2019-9805,
CVE-2019-9806, CVE-2019-9807, CVE-2019-9808, CVE-2019-9809)

A mechanism was discovered that removes some bounds checking for string, array,
or typed array accesses if Spectre mitigations have been disabled. If a user
were tricked in to opening a specially crafted website with Spectre mitigations
disabled, an attacker could potentially exploit this to cause a denial of
service, or execute arbitrary code. (CVE-2019-9793)

It was discovered that Upgrade-Insecure-Requests was incorrectly enforced for
same-origin navigation. An attacker could potentially exploit this to conduct
man-in-the-middle (MITM) attacks. (CVE-2019-9803)

Update instructions

The problem can be corrected by updating your system to the following package
versions:

Ubuntu 18.10
    firefox - 66.0+build3-0ubuntu0.18.10.1
Ubuntu 18.04 LTS
    firefox - 66.0+build3-0ubuntu0.18.04.1
Ubuntu 16.04 LTS
    firefox - 66.0+build3-0ubuntu0.16.04.2

To update your system, please follow these instructions: https://
wiki.ubuntu.com/Security/Upgrades .

After a standard system update you need to restart Firefox to make all the
necessary changes.
