+	Zydis users of versions v3.2.0 and older
+	that use the string functions provided in zycore in order to
+	append untrusted user data to the formatter buffer within
+	their custom formatter hooks can run into heap buffer
+	overflows. Older versions of Zydis failed to properly
+	initialize the string object within the formatter buffer,
+	forgetting to initialize a few fields, leaving their value
+	to chance. This could then in turn cause zycore functions
+	like ZyanStringAppend to make incorrect calculations for the
+	new target size, resulting in heap memory corruption.
