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)");

  script_tag(name:"affected", value:"'icedtea-web' package(s) on Ubuntu 11.10, Ubuntu 12.04.");

  script_tag(name:"solution", value:"Please install the updated package(s).");
