GLSA-200812-09 : OpenSC: Insufficient protection of smart card PIN

medium Nessus Plugin ID 35084

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200812-09 (OpenSC: Insufficient protection of smart card PIN)

 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 :

 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.
 Workaround :

 There is no known workaround at this time.

Solution

All OpenSC users should upgrade to the latest version, and then check and update their smart cards:
 # emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/opensc-0.11.6' # pkcs15-tool --test-update # pkcs15-tool --test-update --update
