Ubuntu Security Notice USN-1804-1
April 18, 2013
icedtea-web vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS
Summary:
Two security issues were fixed in IcedTea-Web.
Software Description:
- icedtea-web: A web browser plugin to execute Java applets
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 12.10:
icedtea-netx 1.3.2-1ubuntu0.12.10.1
Ubuntu 12.04 LTS:
icedtea-netx 1.2.3-0ubuntu0.12.04.1
Ubuntu 11.10:
icedtea-netx 1.2.3-0ubuntu0.11.10.1
Ubuntu 10.04 LTS:
icedtea-netx 1.2.3-0ubuntu0.10.04.1
After a standard system update you need to restart your browser to make
all the necessary changes.
