(RHSA-2013:0523) Low: ccid security and bug fix update

Chip/Smart Card Interface Devices (CCID) is a USB smart card reader
standard followed by most modern smart card readers. The ccid package
provides a Generic, USB-based CCID driver for readers, which follow this
standard.

An integer overflow, leading to an array index error, was found in the way
the CCID driver processed a smart card’s serial number. A local attacker
could use this flaw to execute arbitrary code with the privileges of the
user running the PC/SC Lite pcscd daemon (root, by default), by inserting a
specially-crafted smart card. (CVE-2010-4530)

This update also fixes the following bug:

• Previously, CCID only recognized smart cards with 5V power supply. With
  this update, CCID also supports smart cards with different power supply.

All users of ccid are advised to upgrade to this updated package, which
contains backported patches to correct these issues.
