OSSNs should be line-wrapped at 72 characters to behave properly in MUAs. This corrects the line-wrapping for the recently merged OSSN-0046. Change-Id: I500867a6862fbb372faced682926e216d880c26c

Setting services to debug mode can also set Pecan to debug
|
||
---
|
||
|
||
### Summary ###
|
||
When debug mode is set for a service using Pecan (via --debug or
|
||
CONF.debug=True) Pecan is also set to debug. This can result in
|
||
accidental information disclosures.
|
||
|
||
### Affected Services / Software ###
|
||
Blazar, Ceilometer, Cue, Gnocchi, Ironic, Kite, Libra, Pecan, Tuskar
|
||
|
||
### Discussion ###
|
||
Although it's best practice to run production environments with
|
||
debugging functionality disabled, experience shows us that many
|
||
deployers choose to run OpenStack with debugging enabled to aid with
|
||
administration and fault finding.
|
||
|
||
When Pecan is running in debug mode, the following capabilities are made
|
||
available to anyone who can interact with the API service:
|
||
|
||
* Retrieve a stack trace of failed Pecan calls
|
||
* Retrieve a full list of environment variables containing potentially
|
||
sensitive information such as API credentials, passwords etc.
|
||
* Set an execution breakpoint which hangs the service with a pdb shell,
|
||
resulting in a denial of service
|
||
|
||
### Recommended Actions ###
|
||
At time of writing, Ceilometer, Gnocchi and Ironic have released fixes.
|
||
Deployers are encouraged to apply these fixes (see launchpad bug in
|
||
References) in their clouds. For services that do not have a fix, or
|
||
where fixes cannot be applied in existing deployments, we advise not
|
||
using the debug configuration for affected services in production
|
||
environments.
