========================================================================== Ubuntu Security Notice USN-1804-2 April 23, 2013 icedtea-web regression ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS - Ubuntu 11.10 Summary: Due to a regression, IcedTea-Web might not be able to access some sites. Software Description: - icedtea-web: A web browser plugin to execute Java applets Details: USN-1804-1 fixed vulnerabilities in IcedTea-Web. This update introduced a regression with the Java Network Launching Protocol (JNLP) when fetching content over SSL under certain configurations, such as when using the community-supported IcedTead 7 browser plugin. This update fixes the problem. We apologize for the inconvenience. Original advisory details: Jiri Vanek discovered that IcedTea-Web would use the same classloader for applets from different domains. A remote attacker could exploit this to expose sensitive information or potentially manipulate applets from other domains. (CVE-2013-1926) It was discovered that IcedTea-Web did not properly verify JAR files and was susceptible to the GIFAR attack. If a user were tricked into opening a malicious website, a remote attacker could potentially exploit this to execute code under certain circumstances. (CVE-2013-1927) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: icedtea-7-plugin 1.2.3-0ubuntu0.12.04.2 icedtea-netx 1.2.3-0ubuntu0.12.04.2 Ubuntu 11.10: icedtea-netx 1.2.3-0ubuntu0.11.10.2 After a standard system update you need to restart your browser to make all the necessary changes.
