The program overwrites memory adjacent to the buffer, which may contain other information or code. L’ write overflow ( buffer overflow) occurs when a program writes data into a buffer beyond the limits of the buffer itself. In this area, data buffers of varying sizes are allocated. The term heap refers to a region of memory used for dynamic allocation of data during the execution of a program. These problems can lead to serious security consequences, including running arbitrary code by an attacker. Type vulnerabilities heap buffer write overflow occur when an application writes data beyond the limits of a buffer allocated in heap memory. The most serious of the four problems, marked with the identifier CVE-2023-40031is related to a type problem heap buffer write overflow. Yet, at the end of last August the researcher Jaroslav Lobacevski reported the discovery of four vulnerability security in Notepad++. Which is decidedly less common, precisely due to the characteristics of a text fileis that an editor like Notepad++ presents the risk of arbitrary code execution. To avoid these problems, it is always advisable to install the patch released monthly by Microsoft. In the case of complex applications such as the components of suite Officethere is often a risk that simply opening or viewing a document (even through the File Explorer preview) could lead to the execution of malicious code. Notepad++ to update but there is no risk of arbitrary code execution
