> We hit a problem in winutils when running tests on Windows. The static code analysis
change will fix the problem. More specifically, the old code always assumes the security descriptor
get from GetSecurityDescriptorControl() is relative, and will make an absolute security descriptor
out of it. The new absolute security descriptor will then pass to SetSecurityDescriptorDacl()
to set permissions on the file. If the security descriptor is absolute, the new absolute security
descriptor will be NULL, and we will run into the problem. This is what happened exactly in
our case. The fix from static code analysis will solve the problem.
