"The remote host is running a version of macOS / Mac OS X that is 10.15.x prior to 10.15.5, 10.13.x prior to 10.13.6
Security Update 2020-003, 10.14.x prior to 10.14.6 Security Update 2020-003. It is, therefore, affected by multiple
vulnerabilities:
- In ksh version 20120801, a flaw was found in the way it
evaluates certain environment variables. An attacker
could use this flaw to override or bypass environment
restrictions to execute shell commands. Services and
applications that allow remote unauthenticated attackers
to provide one of those environment variables could
allow them to exploit this issue remotely.
(CVE-2019-14868)
- In Zsh before 5.8, attackers able to execute commands
can regain privileges dropped by the --no-PRIVILEGED
option. Zsh fails to overwrite the saved uid, so the
original privileges can be restored by executing
MODULE_PATH=/dir/with/module zmodload with a module that
calls setuid(). (CVE-2019-20044)
- An out-of-bounds read was addressed with improved input
validation. This issue is fixed in iOS 13.3.1 and iPadOS
13.3.1, macOS Catalina 10.15.3, tvOS 13.3.1, watchOS
6.1.2. Processing a maliciously crafted image may lead
to arbitrary code execution. (CVE-2020-3878)
Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported
version number.");
