CVE-2015-5235

Updated icedtea-web packages fix security vulnerabilities:

It was discovered that IcedTea-Web did not properly sanitize applet URLs when storing applet trust settings. A malicious web page could use this flaw to inject trust-settings configuration, and cause applets to be executed without user approval (CVE-2015-5234).

It was discovered that IcedTea-Web did not properly determine an applet's origin when asking the user if the applet should be run. A malicious page could use this flaw to cause IcedTea-Web to execute the applet without user approval, or confuse the user into approving applet execution based on an incorrectly indicated applet origin (CVE-2015-5235).

These are all security issues fixed in the icedtea-web-javadoc-1.6.2-3.3 package on the GA media of openSUSE Tumbleweed.

The Java IcedTea-Web Plugin was updated to 1.6.1 bringing various features, bug- and securityfixes.

IcedTea-Web before 1.5.3 and 1.6.x before 1.6.1 does not properly determine the origin of unsigned applets, which allows remote attackers to bypass the approval process or trick users into approving applet execution via a crafted web page.

It was discovered that IcedTea Web incorrectly handled applet URLs. A remote attacker could possibly use this issue to inject applets into the .appletTrustSettings configuration file and bypass user approval. (CVE-2015-5234)

Andrea Palazzo discovered that IcedTea Web incorrectly determined the origin of unsigned applets. A remote attacker could possibly use this issue to bypass user approval, or to trick the user into approving applet execution. (CVE-2015-5235)
