Hello Josh, Steve, vendors,
Rafael Dominguez Vega of MWR InfoSecurity reported two more flaws related with smart cards:
I), CCID: Integer overflow, leading to array index error when processing crafted serial number of certain cards
Description:
An integer overflow, leading to array index error was found
in the way USB CCID (Chip/Smart Card Interface Devices) driver
processed certain values of card serial number. 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
with specially-crafted value of its serial number, inserted to
the system USB port.

II), pcsc-lite: Stack-based buffer overflow in Answer-to-Reset (ATR) decoder
Description:
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.

Could you allocate CVE ids for these two too?
Thanks && Regards, Jan.
