The Shellshock Bug - Unintended Consequences in Reuse of Software

Last week a serious, remotely exploitable vulnerability was discovered in the widely deployed Bourne Again Shell (BASH)*.
The vulnerability exists already for a long time (now), and is present due mainly to wrong standard configuration and enabling of unnecessary features.
The technical background is analysed by ENISA in a new flash note.
 
*BASH: a command line interpreter. It is factually present in every Linux- and Mac-System in the internet, as well as in many embedded devices and home routers.
