TYPO3 Core

The remove format function w/ msword selected removes too much content. This seems to affect all Versions of TYPO3 CMS 4.7 to 6.2.1!

File typo3/sysext/rtehtmlarea/htmlarea/plugins/RemoveFormat/remove-format.js, line 244-246:

// Remove unwanted tags and their contents: style, title
html = html.replace(/<style[^>]*>.*<\/style[^>]*>/gi, "").
replace(/<title[^>]*>.*<\/title[^>]*>/gi, "");

This removes too much content if more than one <style> block is found inside the content.
Patch:

// Remove unwanted tags and their contents: style, title
html = html.replace(/<style[^>]*>.*?<\/style[^>]*>/gi, "").
replace(/<title[^>]*>.*<\/title[^>]*>/gi, "");
