The version of mozilla-firefox installed on the remote host is prior to 115.5.0esr. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-325-02 advisory.

  - On some systemsdepending on the graphics settings and driversit was possible to force an out-of-bounds     read and leak memory data into the images created on the canvas element. This vulnerability affects     Firefox < 120, Firefox < 115.5, and Thunderbird < 115.5.0. (CVE-2023-6204)

  - It was possible to cause the use of a MessagePort after it had already been freed, which could potentially     have led to an exploitable crash. This vulnerability affects Firefox < 120, Firefox < 115.5, and     Thunderbird < 115.5.0. (CVE-2023-6205)

  - The black fade animation when exiting fullscreen is roughly the length of the anti-clickjacking delay on     permission prompts. It was possible to use this fact to surprise users by luring them to click where the     permission grant button would be about to appear. This vulnerability affects Firefox < 120, Firefox <     115.5, and Thunderbird < 115.5.0. (CVE-2023-6206)

  - Ownership mismanagement led to a use-after-free in ReadableByteStreams This vulnerability affects Firefox     < 120, Firefox < 115.5, and Thunderbird < 115.5.0. (CVE-2023-6207)

  - When using X11, text selected by the page using the Selection API was erroneously copied into the primary     selection, a temporary storage not unlike the clipboard. *This bug only affects Thunderbird on X11. Other     systems are unaffected.* This vulnerability affects Firefox < 120, Firefox < 115.5, and Thunderbird <     115.5.0. (CVE-2023-6208)

  - Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal /../ part in the     path could be used to override the specified host. This could contribute to security problems in web     sites. This vulnerability affects Firefox < 120, Firefox < 115.5, and Thunderbird < 115.5.0.
    (CVE-2023-6209)

  - Memory safety bugs present in Firefox 119, Firefox 115.4, and Thunderbird 115.4. 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. This vulnerability affects Firefox < 120, Firefox < 115.5, and     Thunderbird < 115.5.0. (CVE-2023-6212)

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