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. This vulnerability affects Firefox < 136.

The remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-100adaf12d advisory.

    - Updated to latest upstream (136.0)

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

The remote Fedora 41 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-60c0e24d76 advisory.

    - Updated to latest upstream (136.0)

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

The version of Firefox installed on the remote macOS or Mac OS X 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)
