Description Moritz Muehlenhoff

2012-07-30 10:53:48 CEST

CVE-2012-3817

Große Mengen von DNSSEC-Validierungsanfragen können zu DoS durch ein fehlerhaftes assert() führen.

Da DNSSEC in UCS nicht direkt unterstützt wird, nur geringe Priorität.

Comment 1 Moritz Muehlenhoff

\item Ein zu striktes assert() erlaubt Denial of Service gegen rekursive Nameserver (CVE-2012-4244)

Comment 2 Moritz Muehlenhoff

2012-10-10 16:16:46 CEST

\item Denial of Service im Handling von RDATA-Records (CVE-2012-5166)

Comment 3 Moritz Muehlenhoff

Eine weitere für UCS harmlose Lücke (die betroffene Option ist in der UCS-Konfiguration nicht aktiviert):

DoS in der Verarbeitung von DNS64-Paketen (CVE-2012-5688)

2.4 ist nicht betroffen.

Comment 4 Moritz Muehlenhoff

Denial of Service in the DNS64 implementation (CVE-2012-5689)

> 2.4 is not affected)
CVE-2013-2494 is for isc-dhcp (which is not affected in the version (< 4.2) in UCS)
This issue for bind9 is CVE-2013-2266
