The remote Ubuntu host is missing one or more security-related patches.
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.
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 the affected icedtea-7-plugin and / or icedtea-netx packages.
