14 DAY TRIAL // Canonical published details about the devscripts vulnerability in its Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04 LTS, and Ubuntu 10.04 LTS operating systems.
According to the company, devscripts could be made to run programs if it opened a specially crafted file..
It has been discovered that the uscan tool incorrectly repacked archive files. If a user or automated system were tricked into processing specially crafted files, a remote attacker could possibly execute arbitrary code.
For a more detailed description of the problems, you can see Canonical's security notification.
The security flaws can be fixed if you upgrade your system(s) to the latest devscripts package specific to each distribution. To apply the patch, run the Update Manager application.
In general, a standard system update will make all the necessary changes and a restart will not be needed.
