Firefox Snap Package on Ubuntu 17.10The latest version of Mozilla Firefox is available as a Snap package for Ubuntu and other Linux distros.

USN-3596-1: Firefox vulnerabilities

firefox vulnerabilities

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

  • Ubuntu 17.10
  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS

Summary

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

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 or opening new tabs, escape the sandbox, bypass same-origin
restrictions, obtain sensitive information, confuse the user with
misleading permission requests, or execute arbitrary code. (CVE-2018-5125,
CVE-2018-5126, CVE-2018-5127, CVE-2018-5128, CVE-2018-5129, CVE-2018-5130,
CVE-2018-5136, CVE-2018-5137, CVE-2018-5140, CVE-2018-5141, CVE-2018-5142)

It was discovered that the fetch() API could incorrectly return cached
copies of no-store/no-cache resources in some circumstances. A local
attacker could potentially exploit this to obtain sensitive information in
environments where multiple users share a common profile. (CVE-2018-5131)

Multiple security issues were discovered with WebExtensions. If a user
were tricked in to installing a specially crafted extension, an attacker
could potentially exploit these to obtain sensitive information or bypass
security restrictions. (CVE-2018-5132, CVE-2018-5134, CVE-2018-5135)

It was discovered that the value of app.support.baseURL is not sanitized
properly. If a malicious local application were to set this to a specially
crafted value, an attacker could potentially exploit this to execute
arbitrary code. (CVE-2018-5133)

It was discovered that javascript: URLs with embedded tab characters could
be pasted in to the addressbar. If a user were tricked in to copying a
specially crafted URL in to the addressbar, an attacker could exploit this
to conduct cross-site scripting (XSS) attacks. (CVE-2018-5143)

Ubuntu 17.10
firefox59.0+build5-0ubuntu0.17.10.1
