DESCRIPTION:
A vulnerability has been reported in PCSC-Lite, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
potentially compromise a vulnerable system.

The vulnerability is caused due to a boundary error within the
"ATRDecodeAtr()" function in src/atrhandler.c, which can be exploited
to cause a buffer overflow via a specially crafted ATR sent by a
malicious smart card.

The vulnerability is reported in versions 1.5.3. Other versions may
also be affected.

SOLUTION:
Update to version 1.6.6.
