Hi all
We have just received information about changes in
SP 2 for XP that can / impact on applications. This is probably of
interest to all developers here.
Read the following link for an
overview..
This link is MS training centre for developers and
provides details of what will break.
http://msdn.microsoft.com/security/productinfo/XPSP2/introduction.aspx A part from TCP/IP implications the memory
protection stuff is interesting, MS says...
Another product that
Microsoft needs to update is the .Net Framework. The new memory protection
features in SP2 require developers of certain applications to mark their code
with memory execution permissions. If they don't, the protection features could
interfere with the application, according to Microsoft.
"The great bulk of applications will not be affected by memory protection. The number one that leaps to mind is execution environments with just-in-time code generation. The .Net Framework is one," Goodhew said. Interesting the implications of the above statement
is that not many apps have been written in .Net. But after examining the
docs it turns out that XP will detect and turn off this feature for all .Net
applications. The new version of .Net will have the ability to add the
above mentioned code blocks. Interestingly this seems to impact Java
badly. Also who knows how the Delphi compiler works, will current and
older versions of Delphi have problems? Currently all the APIs seem to be
.Net only (the typical MS force you to use a product system).
Other funny quotes....
If developers do find
that SP2 breaks their applications, it most likely means that they were not
following best practices in terms of security when writing their applications,
according to Goodhew.
later
Microsoft's Visual
Studio .Net is one of the applications affected by Windows XP SP2. The developer
tool's remote debugging feature won't work because of the improved Windows
Firewall, previously called Internet Connection Firewall, which will be turned
on by default and will close all ports, Goodhew said.
