4.11. ccid
An updated ccid package that fixes one security issue and one bug is now available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
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.
Security Fix
- CVE-2010-4530
- 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.
Bug Fix
- BZ#907821
- The pcscd service failed to read from the SafeNet Smart Card 650 v1 when it was inserted into a smart card reader. The operation failed with a "IFDHPowerICC() PowerUp failed" error message. This was due to the card taking a long time to respond with a full Answer To Reset (ATR) request, which lead to a timeout, causing the card to fail to power up. This update increases the timeout value so that the aforementioned request is processed properly, and the card is powered on as expected.
All ccid users are advised to upgrade to this updated package, which contains backported patches to correct these issues.
