GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute code.

Exploitation status

  • CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
  • US federal civilian agencies are required to remediate it by 2022-07-28. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.

Required action

Apply updates per vendor instructions.
