Примечания
The scope of the CVE is for all of these reported TIFF problems.
The ultimate vulnerability was use of:
strlcpy(attribute,text,Min(sizeof(attribute),(count+1)));
three times in coders/tiff.c, where strlcpy is not an appropriate
function choice for this type of scenario of untrusted-data copying.
