What’s new in SecureDrop 2.2.1?

For administrators

• Security: This release updates the hardened Linux kernel used by SecureDrop from version 5.5.18 to version 5.5.26, which includes a fix for the recently discovered “Dirty Pipe” privilege escalation vulnerability. While a successful exploit would require that an attacker has already obtained code execution capabilities on the system, this kernel update provides important defense in depth. (Issue, Pull Request)

What administrators need to do

SecureDrop Application and Monitor Servers will be updated to SecureDrop 2.2.1 automatically within 24 hours of the release. As with previous releases, we recommend that you update your Tails workstations to the latest version of Tails and the latest version of SecureDrop. Please see our upgrade guide for instructions.
