SciLinux: CVE-2010-0097 Moderate: bind SL5.x i386/x86_64
Summary
CVE-2010-0290 BIND upstream fix for CVE-2009-4022 is incompleteA flaw was found in the BIND DNSSEC NSEC/NSEC3 validation code. If BINDwas running as a DNSSEC-validating resolver, it could incorrectly cacheNXDOMAIN responses, as if they were valid, for records proven by NSEC orNSEC3 to exist. A remote attacker could use this flaw to cause a BINDserver to return the bogus, cached NXDOMAIN responses for valid recordsand prevent users from retrieving those records (denial of service).(CVE-2010-0097)The original fix for CVE-2009-4022 was found to be incomplete. BIND wasincorrectly caching certain responses without performing proper DNSSECvalidation. CNAME and DNAME records could be cached, without properDNSSEC validation, when received from processing recursive clientqueries that requested DNSSEC records but indicated that checking shouldbe disabled. A remote attacker could use this flaw to bypass the DNSSECvalidation check and perform a cache poisoning attack if the target BINDserver was receiving such client queries. (CVE-2010-0290)After installing the update, the BIND daemon (named) will be restartedautomatically.SL 5.xSRPMS:bind-9.3.6-4.P1.el5_4.2.src.rpmi386:bind-9.3.6-4.P1.el5_4.2.i386.rpmbind-chroot-9.3.6-4.P1.el5_4.2.i386.rpmbind-devel-9.3.6-4.P1.el5_4.2.i386.rpmbind-libbind-devel-9.3.6-4.P1.el5_4.2.i386.rpmbind-libs-9.3.6-4.P1.el5_4.2.i386.rpmbind-sdb-9.3.6-4.P1.el5_4.2.i386.rpmbind-utils-9.3.6-4.P1.el5_4.2.i386.rpmcaching-nameserver-9.3.6-4.P1.el5_4.2.i386.rpmx86_64:bind-9.3.6-4.P1.el5_4.2.x86_64.rpmbind-chroot-9.3.6-4.P1.el5_4.2.x86_64.rpmbind-devel-9.3.6-4.P1.el5_4.2.i386.rpmbind-devel-9.3.6-4.P1.el5_4.2.x86_64.rpmbind-libbind-devel-9.3.6-4.P1.el5_4.2.i386.rpmbind-libbind-devel-9.3.6-4.P1.el5_4.2.x86_64.rpmbind-libs-9.3.6-4.P1.el5_4.2.i386.rpmbind-libs-9.3.6-4.P1.el5_4.2.x86_64.rpmbind-sdb-9.3.6-4.P1.el5_4.2.x86_64.rpmbind-utils-9.3.6-4.P1.el5_4.2.x86_64.rpmcaching-nameserver-9.3.6-4.P1.el5_4.2.x86_64.rpm-Connie Sieh-Troy Dawson
