HF1213762 keeps customized exploit prevention application protection rules from being deleted when new exploit content is made available.
If you use Customized Application Protection Rules for Exploit Prevention this hotfix is mandatory. This hotfix must be applied before you implement the next Exploit Content posting, which is scheduled for October 17th. Failure to do so will result in loss of your Customized Application Protection Rules when they are reset to default. Manually recreating the custom policies is required.
