This issue is fixed in iOS 15.1 and iPadOS 15.1, macOS Monterey 12.0.1, iOS     14.8.1 and iPadOS 14.8.1, tvOS 15.1, watchOS 8.1, Security Update 2021-007 Catalina, macOS Big Sur 11.6.1.
    Processing a maliciously crafted image may lead to arbitrary code execution. (CVE-2021-30917)

  - An out-of-bounds write was addressed with improved input validation. This issue is fixed in iOS 15.1 and     iPadOS 15.1, macOS Monterey 12.0.1, iOS 14.8.1 and iPadOS 14.8.1, tvOS 15.1, watchOS 8.1, Security Update     2021-007 Catalina, macOS Big Sur 11.6.1. Processing a maliciously crafted PDF may lead to arbitrary code     execution. (CVE-2021-30919)

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