Summary     : PC/SC Lite smart card framework and applications
Description :
The purpose of PC/SC Lite is to provide a Windows(R) SCard interface
in a very small form factor for communicating to smartcards and
readers.  PC/SC Lite uses the same winscard API as used under
Windows(R).  This package includes the PC/SC Lite daemon, a resource
manager that coordinates communications with smart card readers and
smart cards that are connected to the system, as well as other command
line tools.

Update Information:

This update fixes the following security issue:

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.
