Icedtea-Web Exploit Fixed in Multiple Ubuntu OSes

Perform a simple system update in order to solve the problem

On November 7, in a security notice, Canonical published details about an Icedtea-Web vulnerability for its Ubuntu 12.10, Ubuntu 12.04 LTS, Ubuntu 11.10, Ubuntu 11.04, and Ubuntu 10.04 LTS operating systems.

According to Canonical, the Icedtea-Web plugin could have been made to crash or run programs as your login if it opened a specially crafted web page.

It was discovered that if a user was tricked into opening a malicious website, an attacker could have caused the plugin to crash or possibly execute arbitrary code, as the user invoking the program.

Users can simply fix the security flaws by upgrading the operating systems to the latest icedtea-7-plugin and icedtea-6-plugin, specific to each distribution.

A normal system update, executed with the Update Manager, will implement all the necessary changes. A complete system restart is not necessary.
