Description Thomas Biege 2010-10-08 11:35:56 UTC
There is a security bug in package 'bind'.

This bug is public.

There is no coordinated release date (CRD) set.

CVE number: CVE-2010-0213
CVE description: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-0213

Original posting:

BIND 9.7.1 and 9.7.1-P1, when a recursive validating server has a trust anchor 
that is configured statically or via DNSSEC Lookaside Validation (DLV), allows 
remote attackers to cause a denial of service (infinite loop) via a query for 
an RRSIG record whose answer is not in the cache, which causes BIND to 
repeatedly send RRSIG queries to the authoritative servers.
Comment 1 Uwe Gansert 2010-10-08 13:32:50 UTC
only openSUSE 11.3 with 9.7.1 is affected
I'll do an update to 9.7.1P2
Comment 2 Uwe Gansert 2010-10-12 08:48:52 UTC
I submitted an updated version (the step from 9.7.1 to 9.7.1-P2 only contains the security fix and two bugfixes - so I don't think a backport makes sense).


openSUSE 11.3 is the only affected version
Comment 3 Thomas Biege 2010-10-15 08:23:37 UTC

Did you indeed submit for 11.3? The .changes shows something
about bnc#625019.

sorry, you are right. I submitted it now
