GLSA-201202-03 : MaraDNS: Denial of Service
Medium Nessus Plugin ID 58099
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201202-03 (MaraDNS: Denial of Service)
MaraDNS does not properly randomize hash functions to protect against hash collision attacks.
A remote attacker could send many specially crafted DNS recursive queries, possibly resulting in a Denial of Service condition.
There is no known workaround at this time.
SolutionAll MaraDNS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-dns/maradns-1.4.09'
