Subject: [PATCH] g10: Fix garbled status messages in NOTATION_DATA
|
|
|
|
* g10/cpr.c (write_status_text_and_buffer): Fix off-by-one
|
|
--
|
|
|
|
Depending on the escaping and line wrapping the computed remaining
|
|
buffer length could be wrong. Fixed by always using a break to
|
|
terminate the escape detection loop. Might have happened for all
|
|
status lines which may wrap.
