The remote Ubuntu 20.04 LTS / 22.04 LTS / 22.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5730-1 advisory.

  • An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in macOS Big Sur 11.7, macOS Ventura 13, iOS 16, iOS 15.7 and iPadOS 15.7, watchOS 9, macOS Monterey 12.6, tvOS 16.
    Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2022-32888)

  • A correctness issue in the JIT was addressed with improved checks. This issue is fixed in tvOS 16.1, iOS 15.7.1 and iPadOS 15.7.1, macOS Ventura 13, watchOS 9.1, Safari 16.1, iOS 16.1 and iPadOS 16. Processing maliciously crafted web content may disclose internal states of the app. (CVE-2022-32923)

  • The issue was addressed with improved UI handling. This issue is fixed in tvOS 16.1, macOS Ventura 13, watchOS 9.1, Safari 16.1, iOS 16.1 and iPadOS 16. Visiting a malicious website may lead to user interface spoofing. (CVE-2022-42799)

  • A type confusion issue was addressed with improved memory handling. This issue is fixed in tvOS 16.1, macOS Ventura 13, watchOS 9.1, Safari 16.1, iOS 16.1 and iPadOS 16. Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2022-42823)

  • A logic issue was addressed with improved state management. This issue is fixed in tvOS 16.1, macOS Ventura 13, watchOS 9.1, Safari 16.1, iOS 16.1 and iPadOS 16. Processing maliciously crafted web content may disclose sensitive user information. (CVE-2022-42824)

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