Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
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.
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected icedtea-netx package.
