Package: libgdbm6
Version: 1.23-3
Severity: critical
Justification: breaks unrelated software
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
We are authenticating dovecot users via PAM. Our PAM-Setup includes pam_shield.
pam_shield uses libgdbm6.
As soon as pam_shield is triggered (meaning it blocks an IP) we get a trap
divide error.
Details see below
* What exactly did you do (or not do) that was effective (or
ineffective)?
When removing pam_shield from our PAM-Setup the problem disappears
* What was the outcome of this action?
* What outcome did you expect instead?
Just works.
