The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 115.21. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-15 advisory.

  - Memory safety bugs present in Firefox 135, Thunderbird 135, Firefox ESR 115.20, Firefox ESR 128.7, and     Thunderbird 128.7. 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. (CVE-2025-1937)

  - On 64-bit CPUs, when the JIT compiles WASM i32 return values they can pick up bits from left over memory.
    This can potentially cause them to be treated as a different type. (CVE-2025-1933)

  - In resizeToAtLeast of SkRegion.cpp, there was a possible out of bounds write due to an integer overflow     (CVE-2024-43097)

  - On Windows, a compromised content process could use bad StreamData sent over AudioIPC to trigger a use-     after-free in the Browser process. This could have led to a sandbox escape. (CVE-2025-1930)

  - It was possible to cause a use-after-free in the content process side of a WebTransport connection,     leading to a potentially exploitable crash. (CVE-2025-1931)

The version of Firefox installed on the remote Windows host is prior to 136.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-14 advisory.

  - Malicious pages could use Firefox for Android to pass FIDO: links to the OS and trigger the hybrid     passkey transport. An attacker within Bluetooth range could have used this to trick the user into using     their passkey to log the attacker's computer into the target account. (CVE-2024-9956)

  - On Windows, a compromised content process could use bad StreamData sent over AudioIPC to trigger a use-     after-free in the Browser process. This could have led to a sandbox escape. (CVE-2025-1930)

  - Android apps can load web pages using the Custom Tabs feature. This feature supports a transition     animation that could have been used to trick a user into granting sensitive permissions by hiding what the     user was actually clicking. (CVE-2025-1939)

  - It was possible to cause a use-after-free in the content process side of a WebTransport connection,     leading to a potentially exploitable crash. (CVE-2025-1931)

  - An inconsistent comparator in xslt/txNodeSorter could have resulted in potentially exploitable out-of-     bounds access. Only affected version 122 and later. (CVE-2025-1932)
