The WStr::assign function in kso.dll in Kingsoft WPS Office 10.1.0.7106 and 10.2.0.5978 does not validate the size of the source memory block before an _copy call, which allows remote attackers to cause a denial of service (access violation and application crash) via a crafted (a) web page, (b) office document, or (c) .rtf file.. EPSS estimates a 1.08% chance of exploitation in the next 30 days.
