TITLE:
OpenSC CardOS Improper Initialization Security Issue

SECUNIA ADVISORY ID:
SA31330

VERIFY ADVISORY:
http://secunia.com/advisories/31330/

CRITICAL:
Less critical

IMPACT:
Security Bypass

WHERE:
>From remote

SOFTWARE:
OpenSC 0.x
http://secunia.com/product/19409/

DESCRIPTION:
A security issue has been reported in OpenSC, which can be exploited
by malicious people to bypass certain security restrictions.

The security issue is caused due to the application improperly
setting the ADMIN file control information to "00" while initializing
smart cards having a Siemens CardOS M4 operating system. This can be
exploited to change a user PIN code without having the PIN or PUK if
the smart card was initialized with OpenSC.

The security issue is reported in versions prior to 0.11.5.

SOLUTION:
Update to version 0.11.5.

If a CardOS smart card was initialized with a vulnerable OpenSC
version (test using "pkcs15-tool -T"), apply a smart card update via
the "pkcs15-tool -T -U" command.

PROVIDED AND/OR DISCOVERED BY:
