Thank you for your comments.
The patch was based on the suggested fix from upstream which uses int.
But I agree ssize_t is a better choice.
Updated debdiff attatched.

+  * Fix for CVE-2019-7659
+    Genivia gSOAP 2.7.x and 2.8.x before 2.8.75 allows attackers to cause a
+    denial of service (application abort) or possibly have unspecified other
+    impact if a server application is built with the -DWITH_COOKIES flag. This
+    affects the C/C++ libgsoapck/libgsoapck++ and libgsoapssl/libgsoapssl++
+    libraries, as these are built with that flag.
+  * Fix issue with DIME protocol receiver and malformed DIME headers
+    This patch addresses a critical issue with the DIME protocol receiver that
+    may cause the receiver to become unresponsive when a malformed DIME
+    protocol message is received. -- https://www.genivia.com/advisory.html
