Name of the Vulnerable Software and Affected Versions Vim versions prior to 9.0.1376

Description The issue is related to a heap-based buffer overflow in the Vim text editor, specifically in the utf ptr2char function of the mbyte.c component. This overflow can allow an attacker to access confidential data, compromise data integrity, and cause a denial of service.
