Mozilla Firefox < 69.0

Synopsis

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

Description

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 69.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-25 advisory.

 - Mozilla developers and community members Randell Jesup, Philipp, Cosmin Sabou, and Natalia Csoregi reported memory safety bugs present in Firefox 68. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code.
 (CVE-2019-11734)

 - It is possible to delete an IndexedDB key value and subsequently try to extract it during conversion. This results in a use-after-free and a potentially exploitable crash. (CVE-2019-11752)

 - Logging-related command line parameters are not properly sanitized when Firefox is launched by another program, such as when a user clicks on malicious links in a chat application. This can be used to write a log file to an arbitrary location such as the Windows 'Startup' folder. Note: this issue only affects Firefox on Windows operating systems. (CVE-2019-11751)

 - A use-after-free vulnerability can occur while manipulating video elements if the body is freed while still in use. This results in a potentially exploitable crash. (CVE-2019-11746)

 - Some HTML elements, such as <code><title></code> and <code><textarea></code>, can contain literal angle brackets without treating them as markup. It is possible to pass a literal closing tag to <code>.innerHTML</code> on these elements, and subsequent content after that will be parsed as if it were outside the tag. This can lead to XSS if a site does not filter user input as strictly for these elements as it does for other elements. (CVE-2019-11744)

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 version 69.0 or later.
