Hi,
It seems the detection logic for this patch is off. When doing a scan of a host vulscan reports that it is not needed:
Patch is NOT installed
Checking vulnerability MS15-012_MUI_ENU, rule index 2 ('proofloc2010-kb2956073-fullfile-x86-glb-ENU.exe')
Running detection script
created the hlpr instance ok
isInstallable=False
VUL: 'MS15-012_MUI_ENU' (proofloc2010-kb2956073-fullfile-x86-glb.exe) not detected. Patch proofloc2010-kb2956073-fullfile-x86-glb.exe is not required.
However, doing an MBSA scan says it is needed. In addition, running the patch manually allows it to be installed.
Thanks,
Brad
