A vulnerability has been found and corrected in pcsc-lite:

Stack-based buffer overflow in the ATRDecodeAtr function in the
Answer-to-Reset (ATR) Handler (atrhandler.c) for pcscd in PCSC-Lite
1.5.3, and possibly other 1.5.x and 1.6.x versions, allows physically
proximate attackers to cause a denial of service (crash) and possibly
execute arbitrary code via a smart card with an ATR message containing
a long attribute value (CVE-2010-4531).
