Description Mark J. Cox 2007-11-14 13:57:42 UTC 
http://www.php.net/ChangeLog-5.php#5.2.5

FIX: Fixed htmlentities/htmlspecialchars not to accept partial multibyte
sequences (CVE-2007-5898, Reported by Rasmus Lerdorf)

COMMENT: If a PHP page uses the htmlentities() and htmlspecialchars()
to display untrusted script input in HTML element attributes, a
cross-site-scripting attack may be possible, depending on the browser
used.  [Of Firefox 1.5, 2.0, MSIE 6, 7, only MSIE6 seems vulnerable]

Comment 1 Tomas Hoger 2007-11-29 14:15:37 UTC 
Probable upstream patches:

http://cvs.php.net/viewvc.cgi/php-src/ext/standard/html.c?r1=1.111.2.2.2.14&r2=1.111.2.2.2.14.2.1
http://cvs.php.net/viewvc.cgi/php-src/ext/standard/tests/strings/htmlentities-utf.phpt?r1=1.1&r2=1.2
Comment 2 Mark J. Cox 2007-12-11 08:37:31 UTC 
Unfortunately the CVSSv2 score provided by nvt.nist.gov has been incorrectly coded.

They gave CVSS v2 Base score: 10.0  (High) (AV:N/AC:L/Au:N/C:C/I:C/A:C)

But in fact it should be

CVSS v2 Base score: 4.3 (Medium) (AV:N/AC:M/Au:N/C:N/I:P/A:N)

We've sent a correction to NVD.
