OpenSC is a smart card application that allows reading and writing via
|
|
PKCS#11.

|
|
Chaskiel M Grundman reported that OpenSC uses weak permissions (ADMIN
|
|
file control information of 00) for the 5015 directory on smart cards
|
|
and USB crypto tokens running Siemens CardOS M4.
|

|
|
<impact type="normal">
|
|
<p>
|
|
A physically proximate attacker can exploit this vulnerability to
|
|
change the PIN on a smart card and use it for authentication, leading
|
|
to privilege escalation.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All OpenSC users should upgrade to the latest version, and then check
|
|
and update their smart cards:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/opensc-0.11.6"
|
|
# pkcs15-tool --test-update
|
|
# pkcs15-tool --test-update --update</code>
