can be exploited by malicious people to conduct script insertion
attacks.

The vulnerabilities are caused due to input validation errors in the
processing of Atom and RSS feeds. This can be exploited to inject and
execute arbitrary HTML and script code in context of the feed by
tricking a user into adding a malicious feed and then viewing the
content of it.
