The remote host is affected by the vulnerability described in GLSA-202003-02 (Mozilla Firefox: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page, possibly resulting in the execution of arbitrary code with the       privileges of the process or a Denial of Service condition. Furthermore,       a remote attacker may be able to perform Man-in-the-Middle attacks,       obtain sensitive information, spoof the address bar, conduct clickjacking       attacks, bypass security restrictions and protection mechanisms, or have       other unspecified impact.
  Workaround :

    There is no known workaround at this time.

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 68.4. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-06 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 73.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-05 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 68.5. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-07 advisory.

  - When processing an email message with an ill-formed     envelope, Thunderbird could read data from a random     memory location. (CVE-2020-6793)

  - If a user saved passwords before Thunderbird 60 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 Thunderbird 60.
    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-2020-6794)

  - When processing a message that contains multiple S/MIME     signatures, a bug in the MIME processing code caused a     null pointer dereference, leading to an unexploitable     crash. (CVE-2020-6795)

  - By downloading a file with the .fileloc extension, a     semi-privileged extension could launch an arbitrary     application on the user's computer. The attacker is     restricted as they are unable to download non-     quarantined files or supply command line arguments to     the application, limiting the impact.Note: this     issue only occurs on Mac OSX. Other operating systems     are unaffected. (CVE-2020-6797)

  - If a <template> tag was used in a     <select%gt; tag, the parser could be     confused and allow JavaScript parsing and execution when     it should not be allowed. A site that relied on the     browser behaving correctly could suffer a cross-site     scripting vulnerability as a result.In general, this     flaw cannot be exploited through email in the     Thunderbird product because scripting is disabled when     reading mail, but is potentially a risk in browser or     browser-like contexts. (CVE-2020-6798)

  - When deriving an identifier for an email message,     uninitialized memory was used in addition to the message     contents. (CVE-2020-6792)

  - Mozilla developers and community members Raul Gurzau,     Tyson Smith, Bob Clary, Liz Henry, and Christian Holler     reported memory safety bugs present in Firefox 72 and     Firefox ESR 68.4. Some of these bugs showed evidence of     memory corruption and we presume that with enough effort     some of these could have been exploited to run arbitrary     code.In general, these flaws cannot be exploited     through email in the Thunderbird product because     scripting is disabled when reading mail, but are     potentially risks in browser or browser-like contexts.
