Mozilla Firefox ESR < 60.2

critical Nessus Plugin ID 275697

Synopsis

A web browser installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 60.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2018-21 advisory.

 - A use-after-free vulnerability can occur when an IndexedDB index is deleted while still in use by JavaScript code that is providing payload values to be stored. This results in a potentially exploitable crash. (CVE-2018-12378)

 - A use-after-free vulnerability can occur when refresh driver timers are refreshed in some circumstances during shutdown when the timer is deleted while still in use. This results in a potentially exploitable crash. (CVE-2018-12377)

 - A same-origin policy violation allowing the theft of cross-origin URL entries when using a <code><meta> meta http-equiv=refresh</code> on a page to cause a redirection to another site using <code>performance.getEntries()</code>. This is a same-origin policy violation and could allow for data theft. (CVE-2018-18499)

 - When the Mozilla Updater opens a MAR format file which contains a very long item filename, an out-of- bounds write can be triggered, leading to a potentially exploitable crash. This requires running the Mozilla Updater manually on the local system with the malicious MAR file in order to occur.
 (CVE-2018-12379)

 - Browser proxy settings can be bypassed by using the automount feature with autofs to create a mount point on the local file system. Content can be loaded from this mounted file system directly using a <code>file:</code> URI, bypassing configured proxy settings. Note: this issue only affects OS X in default configurations. On Linux systems, autofs must be installed for the vulnerability to occur and Windows is not affected. (CVE-2017-16541)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Mozilla Firefox ESR version 60.2 or later.
