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 via a query for cached data . 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 by triggering a rollover . 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 via a DNS query . Packages for 2009.0 are provided as of the Extended Maintenance Program. The updated packages for Mandriva Linux 2009.0, 2010.0 and Mandriva Linux Enterprise Server 5.1 has been upgraded to bind-9.6.2-P3 and patched to address the CVE-2010-3762 security issue.
