Descriptions

Improper verification of the digital signature in ksojscore.dll in Kingsoft WPS Office in versions equal or less than 12.1.0.18276 on Windows allows an attacker to load an arbitrary Windows library. The patch released in version 12.2.0.16909 to mitigate CVE-2024-7262 was not restrictive enough.
