The remote Oracle Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2023-5433 advisory.

    [115.3.1-1.0.1]
    - Update to 115.3.1

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 118.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-41 advisory.

  - A compromised content process could have provided malicious data to <code>FilterNodeD2D1</code> resulting     in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process.
    (CVE-2023-5168)

  - A compromised content process could have provided malicious data in a <code>PathRecording</code> resulting     in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process.
    (CVE-2023-5169)

  - In canvas rendering, a compromised content process could have caused a surface to change unexpectedly,     leading to a memory leak of a privileged process. This memory leak could be used to effect a sandbox     escape if the correct data was leaked. (CVE-2023-5170)

  - During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing     an attacker to write two NUL bytes, and cause a potentially exploitable crash. (CVE-2023-5171)

  - A hashtable  in the Ion Engine could have been mutated while there was a live interior reference, leading     to a potential use-after-free and exploitable crash. (CVE-2023-5172)

  - In a non-standard configuration of Firefox, an integer overflow could have occurred based on network     traffic (possibly under influence of a local unprivileged webpage), leading to an out-of-bounds write to     privileged process memory.  This bug only affects Firefox if a non-standard preference allowing non-HTTPS     Alternate Services (<code>network.http.altsvc.oe</code>) is enabled. (CVE-2023-5173)

  - If Windows failed to duplicate a handle during process creation, the sandbox code may have inadvertently     freed a pointer twice, resulting in a use-after-free and a potentially exploitable crash. This bug only     affects Firefox on Windows when run in non-standard configurations (such as using <code>runas</code>).
    Other operating systems are unaffected. (CVE-2023-5174)

  - During process shutdown, it was possible that an <code>ImageBitmap</code> was created that would later be     used after being freed from a different codepath, leading to a potentially exploitable crash.
    (CVE-2023-5175)

  - Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. 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. (CVE-2023-5176)
