| description | The remote host is running a version of macOS / Mac OS X that is 10.15.x prior to 10.15.3, 10.13.x prior to 10.13.6, 10.14.x prior to 10.14.6. It is, therefore, affected by multiple vulnerabilities: - In PHP versions 7.1.x below 7.1.33, 7.2.x below 7.2.24 and 7.3.x below 7.3.11 in certain configurations of FPM setup it is possible to cause FPM module to write past allocated buffers into the space reserved for FCGI protocol data, thus opening the possibility of remote code execution. (CVE-2019-11043) - An arbitrary code exution vulnerability exists due to a misconfiguration. An authenticated, local attacker can exploit this to execute arbitrary code on the remote host. (CVE-2019-18634) - An arbitrary code exution vulnerability exists due to the ability to process a maliciously crafted image. An unauthenticated, remote attacker can exploit this to execute arbitrary code on the remote host. (CVE-2020-3826 CVE-2020-3827 CVE-2020-3870 CVE-2020-3878) - A privilege escalation vulnerability exists in due to an out-of-bounds read issue. An unauthenticated, remote attacker can exploit this, to gain elevated access to the system. (CVE-2020-3829) - An arbitrary file write vulnerability exists in the handling of symlinks. A malicious program crafted by an attacker can exploit this to overwrite arbitrary files on the remote host. (CVE-2020-3830 CVE-2020-3835 CVE-2020-3855) - An information disclosure vulnerability exists in the access control handling of applications. A malicious application crafted by attacker can exploit this to disclose the kernel memory layout. (CVE-2020-3836) - An arbitrary code exution vulnerability exists due to a memory corruption issue. A malicious application crafted by a remote attacker may be able to execute arbitrary code with kernel privileges on the remote host. (CVE-2020-3837 CVE-2020-3842 CVE-2020-3871) - An arbitrary code exution vulnerability exists due to a permissions logic flaw. A malicious application crafted by a remote attacker may be able to execute arbitrary code with system privileges on the remote host. (CVE-2019-18634 CVE-2020-3854 CVE-2020-3845 CVE-2020-3853 CVE-2020-3857) - An information disclosure vulnerability exists in the input sanitization logic. A malicious application crafted by attacker can exploit this to read restricted memory. (CVE-2020-3839 CVE-2020-3847) - An arbitrary code exution vulnerability exists due to the loading of a maliciously crafted racoon configuration file. An authenticated, local attacker can exploit this to execute arbitrary code on the remote host. (CVE-2020-3840) - A denial of service (DoS) vulnerability exists due to a memory corruption issue. An unauthenticated, remote attacker can exploit this issue, via malicious input, to cause the system to crash, stop responding, or corrupt the kernel memory. (CVE-2020-3843) - An arbitrary code exution vulnerability exists due to either a buffer overflow or out-of-bounds read issue. An authenticated, local attacker can exploit this to execute arbitrary code on the remote host or cause an unexpected application to terminate. (CVE-2020-3846 CVE-2020-3848 CVE-2020-3849 CVE-2020-3850 CVE-2020-3877) - A memory corruption vulnerability exists due to a malicious crafted string. An unauthenticated, remote attacker can exploit this issue, via malicious input, to cause the corruption of the heap memory. (CVE-2020-3856) - An security bypass vulnerability exists in the handling of files from an attacker controlled NFS mount. A remote attacker with local access could search for and open a file from an attacker controlled NFS mount and bypass Gatekeeper Security features. (CVE-2020-3866) - An information disclosure vulnerability exists where an application can read restricted memory. A local, authorized attacker can exploit this to read restricted memory. (CVE-2020-3872 CVE-2020-3875) Note that Nessus has not tested for this issue but has instead relied only on the operating system |
