Package: unrar
Version: 1:5.3.2-1
Severity: normal
Dear Maintainer,
In short: I automatically sent invalid input to the file-overwrite-prompt,
crashing it.
What led up to the situation?
touch b
rar a b.rar b
Now I was copy pasting something like the following command (everthing between
the quotes) into xfce4-terminal:
"unrar x b.rar
e12345678901234567890123456789012345678901234567
0123456789012345678901234567890
"
Note that the clipboard should contain the last newline / linefeed, also the
'e' at the beginning seems to be important, the numbers are not. Now I get the
following output:

When increasing the clipboard to the output changes, e.g.:
"unrar x b.rar
e12345678901234567890123456789012345678901234567
012345678901234567890123456789012345678901234567
"
results in:

It seems to me that the additional two lines after the command are being sent
to the prompt and effectively fuzzying it. Indeed the problem can be reproduced
like this:
echo "e12345678901234567890123456789012345678901234567
012345678901234567890123456789012345678901234567
