CVE Request -- 1, ccid -- int.overflow leading to array index error 2, pcsc-lite stack-based buffer overflow in ATR decoder [was: [oss-security] CVE request: opensc buffer overflow ]

[Jan Lieskovsky <jlieskov () redhat com>]

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.
