- ------------------------------------------------------------------------
Package : opensc
Vulnerability : programming error
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2008-2235
The previous security update for opensc had a too strict check for
vulnerable smart cards. It could flag cards as safe even though they may
be affected. This update corrects that problem. We advise users of the
smart cards concerned to re-check their card after updating the package, following the procedure outlined in the original advisory text below.
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
For the stable distribution (etch), this problem has been fixed in
version 0.11.1-2etch2.
For the unstable distribution (sid), this problem has been fixed in
version 0.11.4-5.
We recommend that you upgrade your opensc package and check your card(s)
with the command described above.
