Description Josh Bressers 2009-01-08 10:19:26 EST
This upstream PHP bug:
http://bugs.php.net/bug.php?id=27421

describes an issue where setting mbstring.func_overload = 7 in a .htaccess file, causes that setting to be set globally for the webserver.  This in turn breaks most unicode text operations, possibly hampering other sites hosted by the webserver.

Common Vulnerabilities and Exposures assigned an identifier CVE-2009-0754 to
the following vulnerability:

Name: CVE-2009-0754
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0754
Assigned: 20090303
Reference: MLIST:[oss-security] 20090130 CVE Request - php (PHP BZ#27421)
Reference: URL: http://www.openwall.com/lists/oss-security/2009/01/30/1
Reference: MLIST:[oss-security] 20090203 Re: CVE Request - php (PHP BZ#27421)

Reference: CONFIRM: http://bugs.php.net/bug.php?id=27421

PHP 4.4.4, 5.1.6, and other versions, when running on Apache, allows
local users to modify behavior of other sites hosted on the same web
server by modifying the mbstring.func_overload setting within
.htaccess, which causes this setting to be applied to other virtual
hosts on the same server.
