Summary

An exploitable information vulnerability exists in the XCF image rendering functionality of Simple DirectMedia Layer SDL2_image-2.0.2. A specially crafted XCF image can cause an out-of-bounds read on the heap, resulting in information disclosure. An attacker can display a specially crafted image to trigger this vulnerability.

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.
