Package: libacr38u
Version: 1.7.10-1
Severity: important
Tags: patch
Using the Smart Card Reader with my new Regional Health Card and try to access
to a reserved Web area with iceweasel (using opensc middleware to access to
the card) I obtain a failure.
The reason is that the driver receive a "0a" response from the card and
understand it as an APDU reply (wrong!) instead of part of a
WTX message - Waiting Time Extension (correct) sended by the card because it
needs more time.
VERY IMPORTANT: the patch is from Emanuele Pucciarelli, I'm only the
bug finder and the obsessive bug-fix supplicant; I had tried to investigate
the bug but Emanuele was more fast to fix it.
