The Wheezy patch left an unresolved symbol in the imklog module of
the Squeeze version. rsyslog worked fine except that messages from the
kernel couldn’t be submitted any longer. This update fixes this issue.

For reference, the original advisory text follows.

  • CVE-2014-3634
    Fix remote syslog vulnerability due to improper handling
    of invalid PRI values.
  • CVE-2014-3683
    Followup fix for CVE-2014-3634. The initial patch was incomplete.
    It did not cover cases where PRI values > MAX_INT caused integer
    overflows resulting in negative values.

For Debian 6 Squeeze, these issues have been fixed in rsyslog version 4.6.4-2+deb6u2
