Bug Description

Binary package hint: clamav-freshclam

Description: Ubuntu 9.04
Release: 9.04

clamav-freshclam:
  Installed: (none)
  Candidate: 0.95.1+dfsg-1ubuntu1.2
  Version table:
     0.95.1+dfsg-1ubuntu1.2 0
        500 http://de.archive.ubuntu.com jaunty-updates/main Packages
        500 http://security.ubuntu.com jaunty-security/main Packages
        100 /var/lib/dpkg/status
     0.95.1+dfsg-1ubuntu1 0
        500 http://de.archive.ubuntu.com jaunty/main Packages

when clamav-freshclam is installed and there exists an entry in /etc/security/pam_mount.conf.xml boot process will hang because freshclam will try a su which triggers a cifs password request. boot process will continue if a password is entered.

What would you propose clamav-freshclam do differently?

scott, thanks for looking into this.

i am not sure whether this can be solved inside clamav-freshclam, i suspect this to be more of a bad interaction between clamav, pam and pam_mount. anyway it would be great if this could be resolved in a way that does not cause the boot process to hang (after all, no other service in the whole init sequence runs into this problem, that's why i reported the bug against freshclam).

i have no deeper knowledge about that freshclam is trying to do and why, but i was thinking along the lines of either switching id without triggering the pam_mount or a change in the way priviledges are gained and dropped in the first place so su-ing would'nt be necessary - just my rough guess, again, i have not digged deeper into the issue.

Debian has a fix for this that we ought to be able to get into Karmic.

Are you running freshclam as a daemon?

Scott

The answer was "no"...

I've since done a fresh install of Ubuntu 9.04 onto a clean disk and
don't have this problem any more. Perhaps it was some old configuration
files.

Version 0.95.2+dfsg-4ubuntu1.2 of clamav, clamav-base, clamav-freshclam
and libclamav6 are installed.

Regards,
Dave

It turns out the potential fix was only relevant if you'd been running it as a daemon.
