Subject: [PATCH] iotests/244: Don't store data-file with protocol in image
|
|
(CVE-2024-4467)
|
|
|
|
We want to disable filename parsing for data files because it's too easy
|
|
to abuse in malicious image files. Make the test ready for the change by
|
|
passing the data file explicitly in command line options.
