14 DAY TRIAL // On June 18, Canonical published in a security notice details about a libKDcraw vulnerability for its Ubuntu 12.04 LTS (Precise Pangolin) operating system.
According to Canonical, libKDcraw could have been made to crash or run programs, as the user's login, if it opened a specially crafted file. It was discovered that libKDcraw incorrectly handled broken full-color images.
If a user or automated system were tricked into processing a specially crafted raw image, applications linked against libKDcraw could be made to crash, resulting in a denial of service.
For a more detailed description of the security problems, you can visit Canonical's security notification.
The security flaws can be fixed if you upgrade your system(s) to the latest libkdcraw20 package. To apply the update, run the Update Manager application.
In general, a standard system update will make all the necessary changes. A system restart will be necessary to implement the changes.
