Description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The IcedTea-Web plugin before 1.2.3 and 1.3.x before 1.3.2 uses the same class loader for applets with the same codebase path but from different domains, which allows remote attackers to obtain sensitive information or possibly alter other applets via a crafted applet. Per http://www.ubuntu.com/usn/USN-1804-1/ "A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 12.10 Ubuntu 12.04 LTS Ubuntu 11.10 Ubuntu 10.04 LTS" Per http://lists.opensuse.org/opensuse-updates/2013-04/msg00106.html "Affected Products: openSUSE 12.2"
