[TYPO3-english] Security

[Filype Pereira]

Hello all,

Im using Typo3 4.2.3 and today on my default template I found this code:

   subparts.FOOTER >
   subparts.FOOTER = TEXT
   subparts.FOOTER.insertData = 1
   subparts.FOOTER.value (
   <p>footer info /p>
<noscript><a href=http://utrium.com/>tramadol</a><a href=http:// 
magiclevitra.org.uk/>levitra</a></noscript>
)


is there any security upgrades that leads someone write on my  
template that i should be aware of?

Thanks,
Filype
