IcedTea-Web before 1.5.3 and 1.6.x before 1.6.1 does not properly sanitize applet URLs, which allows remote attackers to inject applets into the .appletTrustSettings configuration file and bypass user approval to execute the applet via a crafted web page, possibly related to line breaks.

The following packages have been upgraded to a newer upstream version:
icedtea-web (1.6.2).

Security Fix(es) :

  - 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)

An update for icedtea-web is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The IcedTea-Web project provides a Java web browser plug-in and an implementation of Java Web Start, which is based on the Netx project.
It also contains a configuration tool for managing deployment settings for the plug-in and Web Start implementations. IcedTea-Web now also contains PolicyEditor - a simple tool to configure Java policies.

The following packages have been upgraded to a newer upstream version:
icedtea-web (1.6.2). (BZ#1275523)

Security Fix(es) :

* 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)

Red Hat would like to thank Andrea Palazzo (Truel IT) for reporting these issues.

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2016-0778 advisory.

    [1.6.2-1]
    - updated to 1.6.2
    - fixed also rhbz#1303437 - package owns /etc/bash_completion.d but it should not own it

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2817-1 advisory.

    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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
