CVE-2013-1926

Status Candidate

Overview

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.

Mandriva Linux Security Advisory 2013-146

Mandriva Linux Security Advisory 2013-146 - Multiple vulnerabilities has been discovered and corrected in icedtea-web. It was discovered that the IcedTea-Web plug-in incorrectly used the same class loader instance for applets with the same value of the codebase attribute, even when they originated from different domains. A malicious applet could use this flaw to gain information about and possibly manipulate applets from different domains currently running in the browser. The IcedTea-Web plug-in did not properly check the format of the downloaded Java Archive files. This could cause the plug-in to execute code hidden in a file in a different format, possibly allowing attackers to execute code in the context of web sites that allow uploads of specific file types, known as a GIFAR attack. The updated packages have been upgraded to the 1.3.2 version which is not affected by these issues.
