Gentoo Linux Security Advisory GLSA 200812-09 - Smart cards formatted using OpenSC do not sufficiently protect the PIN, allowing attackers to reset it. 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. Versions less than 0.11.6 are affected.
c6ee2a4b61e4dbad6fbde8d1cdb450da973718cd1afa12d10b3c625df252fae9Mandriva Linux Security Advisory - Chaskiel M Grundman found that OpenSC would initialize smart cards with the Siemens CardOS M4 card operating system without proper access rights. This allowed everyone to change the card's PIN without first having the PIN or PUK, or the superuser's PIN or PUK. Please note that this issue can not be used to discover the PIN on a card. If the PIN on a card is the same that was always there, it is unlikely that this vulnerability has been exploited. As well, this issue only affects smart cards and USB crypto tokens based on Siemens CardOS M4, and then only those devices that were initialized by OpenSC. Users of other smart cards or USB crypto tokens, or cards that were not initialized by OpenSC, are not affected. After applying the update, executing 'pkcs15-tool -T' will indicate whether the card is fine or vulnerable. If the card is vulnerable, the security settings need to be updated by executing 'pkcs15-tool -T -U'. The updated packages have been patched to prevent this issue.

This allowed everyone to change the card's PIN.
