The version of Mozilla Firefox installed on the remote macOS or     Mac OS X host is prior to 62. It is, therefore, affected by multiple     critical and high severity vulnerabilities.

The version of Mozilla Firefox installed on the remote macOS host is prior to 62. It is, therefore, affected by multiple vulnerabilities as noted in Mozilla Firefox stable channel update release notes for 2018/09/05. Please refer to the release notes for additional information. Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3761-1 advisory.

    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, or execute     arbitrary code. (CVE-2018-12375, CVE-2018-12376, CVE-2018-12377, CVE-2018-12378)

    It was discovered that if a user saved passwords before Firefox 58 and then later set a primary password,     an unencrypted copy of these passwords would still be accessible. A local user could exploit this to     obtain sensitive information. (CVE-2018-12383)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The version of Mozilla Firefox installed on the remote Windows     host is prior to 62. It is, therefore, affected by multiple critical     and high severity vulnerabilities.

Versions of Mozilla Firefox prior to 62.0 are unpatched for the following vulnerabilities as referenced in the mfsa2018-20 advisory:

 - 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 "file: URI", bypassing configured proxy settings. (CVE-2017-16541)
 - Evidence of memory corruption exists that could be exploited to run arbitrary code. (CVE-2018-12375, CVE-2018-12376)
 - 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 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)
 - 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)
 - Manually dragging and dropping an Outlook email message into the browser will trigger a page navigation when the mail columns are incorrectly interpreted as a URL. (CVE-2018-12381)
 - The displayed addressbar URL can be spoofed on Firefox for Android using 'javascript: URI' in concert with JavaScript to insert text before the loaded domain name, scrolling the loaded domain out of view to the right. This can lead to user confusion. (CVE-2018-12382)
 - If a user saved passwords before Firefox 58 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Firefox 58. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. (CVE-2018-12383)
