==============================================
  Hello,

The CAC(Common Access Card) library, used by Quick Emulator(Qemu) to implement
smartcard support, is vulnerable to a host memory leakage issue. It could occur
while allocating a new APDU object using guest supplied raw byte stream in
'vcard_apdu_new'.


A guest user/process could use this flaw to leak host memory resulting in DoS.
