A buffer overflow was addressed with improved bounds checking. This issue is fixed in macOS Catalina 10.15, tvOS 13, iTunes for Windows 12.10.1, iCloud for Windows 10.7, iCloud for Windows 7.14. Processing a maliciously crafted text file may lead to arbitrary code execution.

The remote host is running a version of macOS or Mac OS X that is 10.15.x prior to 10.15.1, 10.14.x prior to 10.14.6 security update 2019-001, 10.13.x prior to 10.13.6 security update 2019-006. It is, therefore, affected by multiple vulnerabilities :

  - An out-of-bounds read error exists in the accounts component due to improper input validation. A remote     attacker can exploit this, to disclose memory contents. (CVE-2019-8787)

  - A security bypass vulnerability exists in the App Store component due to an improper state management     implementation. A local attacker can exploit this, to login to the account of a previously logged in user     without valid credentials. (CVE-2019-8803)

  - An out-of-bounds read error exists in the IOGraphics component due to improper bounds checking. A local     attacker can exploit this, to cause unexpected system termination or to read kernel memory.     (CVE-2019-8759)

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