Gmane
From: Pat Riehecky <riehecky-13hema8v3vg <at> public.gmane.org>
Subject: Security ERRATA Moderate: pcsc-lite on SL6.x i386/x86_64
Newsgroups: gmane.linux.scientific.errata
Date: Thursday 28th February 2013 22:17:24 UTC (over 3 years ago)
Synopsis:          Moderate: pcsc-lite security and bug fix update
Issue Date:        2013-02-21
CVE Numbers:       CVE-2010-4531
--

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.

* Because the chkconfig settings and the startup files in the /etc/rc.d/
directory were not changed during the update described in the
SLBA-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.

* 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.

After installing this update, the pcscd daemon will be restarted 
automatically.
