Description Jeff Pohlmeyer 2019-11-02 17:23:38 UTC 
With previous versions of busybox the xz applet would report an error and exit with error status if the input was invalid:


echo ThisIsNotXZ | busybox xz -dc ; echo $?

xz: corrupted data
1


But the latest version does not show any error message and exits with zero:

echo ThisIsNotXZ | busybox xz -dc ; echo $?
0


I have not checked for sure, but this might be caused by commit 42f454b13b8d972e85acd7f046065ec69af4d206
