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.

If a user or automated system were tricked into processing a specially crafted TGA image, an attacker could cause a denial of service. (CVE-2016-6132, CVE-2016-6214) It was discovered that the GD library incorrectly handled memory when using gdImageScale(). A remote attacker could possibly use this issue to cause a denial of service or possibly execute arbitrary code. (CVE-2016-6207).
