Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

| 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 |
