I Mitres CVE-ordbog: CVE-2007-6437.
Yderligere oplysninger:

Oriol Carreras opdagede at syslog-ng, en næste generations logningsdæmon, kunne narres til at dereferencere en NULL-pointer gennem misdannede tidsstemplinger, hvilket kunne føre til lammelsesangreb og tilsløring af efterfølgende angreb, som ellers ville blive logget.

Den gamle stabile distribution (sarge) er ikke påvirket.

I den stabile distribution (etch), er dette problem rettet i version 2.0.0-1etch1.

I den ustabile distribution (sid), er dette problem rettet i version 2.0.6-1.

Vi anbefaler at du opgraderer din syslog-ng-pakke.

Rettet i:

Debian GNU/Linux 4.0 (stable)
