Advisories MDVSA-2010:253: bind

Recommended Posts

Multiple vulnerabilities were discovered and corrected in bind:

 

named in ISC BIND 9.6.2 before 9.6.2-P3, 9.6-ESV before 9.6-ESV-R3,

and 9.7.x before 9.7.2-P3 does not properly handle the combination

of signed negative responses and corresponding RRSIG records in the

cache, which allows remote attackers to cause a denial of service

(daemon crash) via a query for cached data (CVE-2010-3613).

 

named in ISC BIND 9.x before 9.6.2-P3, 9.7.x before 9.7.2-P3,

9.4-ESV before 9.4-ESV-R4, and 9.6-ESV before 9.6-ESV-R3 does not

properly determine the security status of an NS RRset during a DNSKEY

algorithm rollover, which might allow remote attackers to cause a

denial of service (DNSSEC validation error) by triggering a rollover

(CVE-2010-3614).

 

ISC BIND before 9.7.2-P2, when DNSSEC validation is enabled, does

not properly handle certain bad signatures if multiple trust anchors

exist for a single zone, which allows remote attackers to cause a

denial of service (daemon crash) via a DNS query (CVE-2010-3762).

 

Packages for 2009.0 are provided as of the Extended Maintenance

Program. Please visit this link to learn more:
