Cacti XSS fixes in 0.8.7g

[Tomas Hoger <thoger () redhat com>]

Hi!

Cacti 0.8.7g was released some days ago:
  http://cacti.net/release_notes_0_8_7g.php

Release notes mention couple of security issue previously fixed in
(withdrawn) 0.8.7f, but adds new protections against couple of XSS
issues.


"XSS 4" from CVE-2009-4032 was not fixed previously:
  https://bugzilla.redhat.com/show_bug.cgi?id=541279#c17

Fixed in include/top_graph_header.php change in:
  http://svn.cacti.net/viewvc?view=rev&revision=6025


Search pattern in log file viewer was not filtered for bad characters,
or escaped before echoing pattern back to page:
  https://bugzilla.redhat.com/show_bug.cgi?id=459105

Possible victims are administrative users with access to log viewer
page.  Fixed in r6025, which adds escaping to other search patterns
too, but others were filtered previously.


Multiple persistent XSS via various item names or descriptions.
Attacker needs to have certain administrative privileges, so this is
fairly lame issue.
  https://bugzilla.redhat.com/show_bug.cgi?id=459229

Originally discovered for template names, where template XML import
provides additional vector (trusted admin tricked to import untrusted
template vs. untrusted admin).  HTML escaping added on various places
in r6037, r6038, r6041 and r6042.
