Detail

Synopsis

Smart cards formatted using OpenSC do not sufficiently protect the PIN, allowing attackers to reset it.

Background

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

Description

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.

Resolution

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

Title: DSA-1627 opensc -- programming error
Description: Chaskiel M Grundman discovered that opensc, a library and utilities to handle smart cards, would initialise smart cards with the Siemens CardOS M4 card operating system without proper access rights. This allowed everyone to change the card's PIN. With this bug anyone can change a user PIN without having the PIN or PUK or the superusers PIN or PUK. However it can not be used to figure out the PIN. If the PIN on your card is still the same you always had, there's a reasonable chance that this vulnerability has not been exploited. This vulnerability affects only smart cards and USB crypto tokens based on Siemens CardOS M4, and within that group only those that were initialised with OpenSC. Users of other smart cards and USB crypto tokens, or cards that have been initialised with some software other than OpenSC, are not affected. After upgrading the package, running pkcs15-tool -T will show you whether the card is fine or vulnerable. If the card is vulnerable, you need to update the security setting using: pkcs15-tool -T -U.
