The remote Ubuntu 20.04 LTS / 21.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5394-1 advisory.

  • A logic issue was addressed with improved state management. This issue is fixed in macOS Monterey 12.3, Safari 15.4, watchOS 8.5, iOS 15.4 and iPadOS 15.4, tvOS 15.4. A malicious website may cause unexpected cross-origin behavior. (CVE-2022-22637)

  • A use after free issue was addressed with improved memory management. This issue is fixed in macOS Monterey 12.3, iOS 15.4 and iPadOS 15.4, tvOS 15.4, Safari 15.4. Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2022-22624)

  • A use after free issue was addressed with improved memory management. This issue is fixed in macOS Monterey 12.3, Safari 15.4, watchOS 8.5, iOS 15.4 and iPadOS 15.4, tvOS 15.4. Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2022-22628)

  • A buffer overflow issue was addressed with improved memory handling. This issue is fixed in macOS Monterey 12.3, Safari 15.4, watchOS 8.5, iTunes 12.12.3 for Windows, iOS 15.4 and iPadOS 15.4, tvOS 15.4.
    Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2022-22629)

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