GLSA-201209-04 : BIND: Multiple vulnerabilities
High Nessus Plugin ID 62237
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201209-04 (BIND: Multiple vulnerabilities)
Multiple vulnerabilities have been discovered in BIND:
Domain names are not properly revoked due to an error in the cache update policy (CVE-2012-1033).
BIND accepts records with zero-length RDATA fields (CVE-2012-1667).
An assertion failure from the failing-query cache could occur when DNSSEC validation is enabled (CVE-2012-3817).
A memory leak may occur under high TCP query loads (CVE-2012-3868).
An assertion error can occur when a query is performed for a record with RDATA greater than 65535 bytes (CVE-2012-4244).
A remote attacker may be able to cause a Denial of Service condition or keep domain names resolvable after it has been deleted from registration.
There is no known workaround at this time.
SolutionAll BIND users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-dns/bind-9.9.1_p3'
