Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated pcsc-lite packages that fix one security issue and three bugs are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

PC/SC Lite provides a Windows SCard compatible interface for communicating with smart cards, smart card readers, and other security tokens.

A stack-based buffer overflow flaw was found in the way pcsc-lite decoded certain attribute values of Answer-to-Reset (ATR) messages. A local attacker could use this flaw to execute arbitrary code with the privileges of the user running the pcscd daemon (root, by default), by inserting a specially crafted smart card. (CVE-2010-4531)

This update also fixes the following bugs :

* Due to an error in the init script, the chkconfig utility did not automatically place the pcscd init script after the start of the HAL daemon. Consequently, the pcscd service did not start automatically at boot time. With this update, the pcscd init script has been changed to explicitly start only after HAL is up, thus fixing this bug.
(BZ#788474, BZ#814549)

* Because the chkconfig settings and the startup files in the /etc/rc.d/ directory were not changed during the update described in the RHBA-2012:0990 advisory, the user had to update the chkconfig settings manually to fix the problem. Now, the chkconfig settings and the startup files in the /etc/rc.d/ directory are automatically updated as expected. (BZ#834803)

* Previously, the SCardGetAttrib() function did not work properly and always returned the 'SCARD_E_INSUFFICIENT_BUFFER' error regardless of the actual buffer size. This update applies a patch to fix this bug and the SCardGetAttrib() function now works as expected. (BZ#891852)

All users of pcsc-lite are advised to upgrade to these updated packages, which fix these issues. After installing this update, the pcscd daemon will be restarted automatically.

Solution
