Debian GNU/Linux 8 and 9:

DLA 1241-1: libkohana2-php security update




Package : libkohana2-php
Version : 2.3.4-2+deb7u1
CVE ID : CVE-2016-10510

David Sopas discovered that Kohana, a PHP framework, was vulnerable to
a Cross-site scripting (XSS) attack that allowed remote attackers to
inject arbitrary web script or HTML by bypassing the strip_image_tags
protection mechanism in system/classes/Kohana/Security.php. This issue
was resolved by permanently removing the strip_image_tags function.
Users are advised to sanitize user input by using external libraries
instead.

For Debian 7 "Wheezy", these problems have been fixed in version
2.3.4-2+deb7u1.

We recommend that you upgrade your libkohana2-php packages.
