Description Vincent Danen 2010-11-12 22:10:38 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2009-5016 to
the following vulnerability:

Name: CVE-2009-5016
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-5016
Assigned: 20101112
Reference: MISC: http://sirdarckcat.blogspot.com/2009/10/couple-of-unicode-issues-on-php-and.html
Reference: MISC: http://www.blackhat.com/presentations/bh-usa-09/VELANAVA/BHUSA09-VelaNava-FavoriteXSS-SLIDES.pdf
Reference: CONFIRM: http://bugs.php.net/bug.php?id=49687

Integer overflow in the xml_utf8_decode function in ext/xml/xml.c in
PHP before 5.2.11 makes it easier for remote attackers to bypass
cross-site scripting (XSS) and SQL injection protection mechanisms via
a crafted string that uses overlong UTF-8 encoding, a different
vulnerability than CVE-2010-3870.

Comment 1 Kurt Seifried 2010-11-13 06:29:14 UTC

CVE duplicate?

CVE-2010-3870 has been assigned to this issue.

Comment 2 Kurt Seifried 2010-11-13 07:32:02 UTC

Oops nevermind. xml_utf8_decode != utf8_decode

Comment 3 Huzaifa S. Sidhpurwala 2010-11-13 10:54:58 UTC

How is this different from:
https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2010-3870 ?

Comment 4 Huzaifa S. Sidhpurwala 2010-11-15 05:09:13 UTC

Ignore my last statement, however it seems that the svn fix for 2010-3870 fixed this issue as well:

http://svn.php.net/viewvc/?view=revision&amp;revision=304959
