Re: The newest Word flaw is due to malformed data structure handling

And without any reasonable technical details it is very difficult to give a title field for the vulnerability.
Several advisories using titles like Word Unspecified Code Execution Vulnerability or Word Code Execution Vulnerability 
#2, #3 are not the trend we want.
Related to the newest Word issue US-CERT assigned a good title:
Microsoft Word malformed pointer vulnerability

I appreciate your efforts to keep the community informed, but these kinds of
"technical details" are completely useless. It's not your fault, this has been a
long-standing problem with the information from coming from the likes of CERT
and MSRC.

Almost all Office vulnerabilities (and security issues in file parsers in
general) are a result of "malfromed data structures allowing memory corruption
to occur". Repeating this statement for every Word bug doesn't tell us anything new.

Descriptions of vulnerabilities, especially ones that are found in the wild,
should include enough information to allow researchers to uniquely identify the
new vulnerability and differentiate it from all other bugs, both known ones and
0days. Without that level of detail, you end up with this:
