Dear Release Team,
The Security Team suggested fixing the TEMP-0678512-2E167C [1] security
issue through a point release.
The issue is a remotely triggerable crash due to stack overflow.
Please see the debdiff attached.
The fix for Wheezy which is very similar was discussed [2] on the Wheezy
LTS list.
Cheers,
Balint
