Machine Type: i686-pc-linux-gnu
Bash Version: 2.05a
Patch Level: 0
Release Status: release
Description:
The string :(){ :|:;:&};: causes problems when run in a bash shell. The error
message "bash: fork: Resource temporarily unavailable" is displayed until you
kill the "script." While this is running, it appears to be a DOS attack
preventing every other user on the machine from running commands. This works
even if you are not root.
Repeat-By:
Run :(){ :|:;:&};: in a bash shell.
