The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4213-1 advisory.

  - It was possible for certain browser prompts and dialogs to be activated or dismissed unintentionally by     the user due to an insufficient activation-delay. This vulnerability affects Firefox < 119, Firefox ESR <     115.4, and Thunderbird < 115.4.1. (CVE-2023-5721)

  - Using iterative requests an attacker was able to learn the size of an opaque response, as well as the     contents of a server-supplied Vary header. This vulnerability affects Firefox < 119. (CVE-2023-5722)

  - An attacker with temporary script access to a site could have set a cookie containing invalid characters     using `document.cookie` that could have led to unknown errors. This vulnerability affects Firefox < 119.
    (CVE-2023-5723)

  - Drivers are not always robust to extremely large draw calls and in some cases this scenario could have led     to a crash. This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and Thunderbird < 115.4.1.
    (CVE-2023-5724)

  - A malicious installed WebExtension could open arbitrary URLs, which under the right circumstance could be     leveraged to collect sensitive user data. This vulnerability affects Firefox < 119, Firefox ESR < 115.4,     and Thunderbird < 115.4.1. (CVE-2023-5725)

  - A website could have obscured the full screen notification by using the file open dialog. This could have     led to user confusion and possible spoofing attacks. *Note: This issue only affected macOS operating     systems. Other operating systems are unaffected.* This vulnerability affects Firefox < 119, Firefox ESR <     115.4, and Thunderbird < 115.4.1. (CVE-2023-5726)

  - The executable file warning was not presented when downloading .msix, .msixbundle, .appx, and .appxbundle     files, which can run commands on a user's computer. *Note: This issue only affected Windows operating     systems. Other operating systems are unaffected.* This vulnerability affects Firefox < 119, Firefox ESR <     115.4, and Thunderbird < 115.4.1. (CVE-2023-5727)

  - During garbage collection extra operations were performed on a object that should not be. This could have     led to a potentially exploitable crash. This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and     Thunderbird < 115.4.1. (CVE-2023-5728)

  - A malicious web site can enter fullscreen mode while simultaneously triggering a WebAuthn prompt. This     could have obscured the fullscreen notification and could have been leveraged in a spoofing attack. This     vulnerability affects Firefox < 119. (CVE-2023-5729)

  - Memory safety bugs present in Firefox 118, Firefox ESR 115.3, and Thunderbird 115.3. 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 < 119, Firefox ESR < 115.4, and     Thunderbird < 115.4.1. (CVE-2023-5730)

  - Memory safety bugs present in Firefox 118. 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 < 119. (CVE-2023-5731)

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