The oldstable distribution (lenny) is not affected.

For the stable distribution (squeeze), this problem has been fixed in version 1.1.1-6.1+squeeze1.

For the unstable distribution (sid), this problem will be fixed soon (the impact in sid is limited to denial of service for both issues).

We recommend that you upgrade your pam packages.");
