Ubuntu Security Notice USN-3844-1
December 11, 2018

firefox vulnerabilities

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

- - Ubuntu 18.10
- - Ubuntu 18.04 LTS
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS


Firefox could be made to crash or run programs as your login if it
opened a malicious website.

Software Description:
- - firefox: Mozilla Open Source web browser


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, bypass same-origin
restritions, or execute arbitrary code. (CVE-2018-12405, CVE-2018-12406,
CVE-2018-12407, CVE-2018-17466, CVE-2018-18492, CVE-2018-18493,
CVE-2018-18494, CVE-2018-18498)

Multiple security issues were discovered in WebExtensions. If a user were
tricked in to installing a specially crafted extension, an attacker could
potentially exploit these to open privileged pages, or bypass other
security restrictions. (CVE-2018-18495, CVE-2018-18497)

Update instructions:

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