The remote host is missing a macOS security update


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.


Upgrade to macos 10.13.6 Security Update 2020-004 / 10.14.6 Security Update 2020-004 / 10.15.6 or later
