Description Jan Lieskovsky 2010-12-22 12:34:01 UTC
A stack-based buffer overflow flaw was found in the way
PC/SC Lite smart card framework decoded certain attribute 
values of the Answer-to-Reset (ATR) message, received back
from the card after connecting. A local attacker could
use this flaw to execute arbitrary code with the privileges
of the user running the pcscd daemon, via a malicious smart
card inserted to the system USB port.
