14 DAY TRIAL // Ubuntu 14.10 and Ubuntu 14.04 LTS operating systems have been updated in order to correct a few Oxide vulnerabilities that have been identified.
A number of Oxide issues have been found and corrected. The Ubuntu maintainers have been quick to upgrade the version in their repos and now it's available for upgrade. Oxide is the Web browser engine library for Qt (QML plugin).
"Several memory corruption bugs were discovered in ICU. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process," reads the security advisory.
For a more detailed description of the problems, you can see Canonical's security notification. Users are advised to upgrade their systems as soon as possible, especially since this is a complicated core component and it needs a lot of attention.
In general, a standard system update will make all the necessary changes. A reboot of the system is not required.
You can also use the terminal to update the system. Just enter these commands in a terminal near you and wait for the process to be over:
sudo apt-get dist-upgrade
