The version of Firefox installed on the remote Windows host is prior to 128.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-29 advisory.

  - When almost out-of-memory an elliptic curve key which was never allocated could have been freed again.
    (CVE-2024-6609)

  - Firefox Android allowed immediate interaction with permission prompts. This could be used for tapjacking.
    (CVE-2024-6605)

  - Clipboard code failed to check the index on an array access. This could have led to an out-of-bounds read.
    (CVE-2024-6606)

  - It was possible to prevent a user from exiting pointerlock when pressing escape and to overlay     customValidity notifications from a <code><select></code> element over certain permission prompts.
    This could be used to confuse a user into giving a site unintended permissions. (CVE-2024-6607)
