description | 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 |
