| Description: | 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. (BZ#808115)
All users of ccid are advised to upgrade to this updated package, which contains backported patches to correct these issues.
