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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - If a website set a large custom cursor, portions of the cursor could have overlapped with the permission     dialog, potentially resulting in user confusion and unexpected granted permissions. This vulnerability     affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8. (CVE-2024-1549)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote AlmaLinux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the ALSA-2024:0955 advisory.

  - When storing and re-accessing data on a networking channel, the length of buffers may have been confused,     resulting in an out-of-bounds memory read. This vulnerability affects Firefox < 123, Firefox ESR < 115.8,     and Thunderbird < 115.8. (CVE-2024-1546)

  - Through a series of API calls and redirects, an attacker-controlled alert dialog could have been displayed     on another website (with the victim website's URL shown). This vulnerability affects Firefox < 123,     Firefox ESR < 115.8, and Thunderbird < 115.8. (CVE-2024-1547)

  - A website could have obscured the fullscreen notification by using a dropdown select input element. This     could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 123,     Firefox ESR < 115.8, and Thunderbird < 115.8. (CVE-2024-1548)

  - If a website set a large custom cursor, portions of the cursor could have overlapped with the permission     dialog, potentially resulting in user confusion and unexpected granted permissions. This vulnerability     affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8. (CVE-2024-1549)

  - A malicious website could have used a combination of exiting fullscreen mode and `requestPointerLock` to     cause the user's mouse to be re-positioned unexpectedly, which could have led to user confusion and     inadvertently granting permissions they did not intend to grant. This vulnerability affects Firefox < 123,     Firefox ESR < 115.8, and Thunderbird < 115.8. (CVE-2024-1550)

  - Set-Cookie response headers were being incorrectly honored in multipart HTTP responses. If an attacker     could control the Content-Type response header, as well as control part of the response body, they could     inject Set-Cookie response headers that would have been honored by the browser. This vulnerability affects     Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8. (CVE-2024-1551)

  - Incorrect code generation could have led to unexpected numeric conversions and potential undefined     behavior.*Note:* This issue only affects 32-bit ARM devices. This vulnerability affects Firefox < 123,     Firefox ESR < 115.8, and Thunderbird < 115.8. (CVE-2024-1552)

  - Memory safety bugs present in Firefox 122, Firefox ESR 115.7, and Thunderbird 115.7. 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 < 123, Firefox ESR < 115.8, and     Thunderbird < 115.8. (CVE-2024-1553)

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