USN-871-1 fixed vulnerabilities in KDE. This update provides the
corresponding updates for KDE 4.

This update also fixes a directory traversal flaw in KDE when processing
help:// URLs. This issue only affected Ubuntu 8.10.

It was discovered that the KDE libraries could use KHTML to process an
unknown MIME type. If a user or application linked against kdelibs were
tricked into opening a crafted file, an attacker could potentially trigger
XMLHTTPRequests to remote sites.
