An out-of-bounds read was addressed with improved input validation. This issue is fixed in macOS Catalina 10.15.6, tvOS 13.4.8, watchOS 6.2.8. A remote attacker may be able to cause unexpected system termination or corrupt kernel memory.

The remote host is running a version of macOS / Mac OS X that is 10.13.x prior to 10.13.6 Security Update 2020-004, 10.14.x prior to 10.14.6 Security Update 2020-004, or 10.15.x prior to 10.15.6. It is, therefore, affected by multiple vulnerabilities, including the following:

  - A vulnerability was discovered in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android that allows a malicious     access point, or an adjacent user, to determine if a connected user is using a VPN, make positive     inferences about the websites they are visiting, and determine the correct sequence and acknowledgement     numbers in use, allowing the bad actor to inject data into the TCP stream. This provides everything that     is needed for an attacker to hijack active connections inside the VPN tunnel. (CVE-2019-14899)

  - cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote     denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an     off-by-one error in _sasl_add_string in common.c in cyrus-sasl. (CVE-2019-19906)

  - In Vim before 8.1.0881, users can circumvent the rvim restricted mode and execute arbitrary OS commands     via scripting interfaces (e.g., Python, Ruby, or Lua). (CVE-2019-20807)

  - rsync 3.1.1 allows remote attackers to write to arbitrary files via a symlink attack on a file in the     synchronization path. (CVE-2014-9512)

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

The version of Apple iOS running on the mobile device is prior to 13.6. It is, therefore, affected by multiple vulnerabilities.
