An out-of-bounds write issue has been discovered in the backspace
handling of the checkType() function in etc.c within the W3M
application. This vulnerability is triggered by supplying a specially
crafted HTML file to the w3m binary. Exploitation of this flaw could
lead to application crashes, resulting in a denial of service condition.
