GLSA-201701-26 : BIND: Denial of Service
Medium Nessus Plugin ID 96420
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201701-26 (BIND: Denial of Service)
A defect in BIND’s handling of responses containing a DNAME answer can cause a resolver to exit after encountering an assertion failure in db.c or resolver.c.
A remote attacker could send a specially crafted DNS request to the BIND resolver possibly resulting in a Denial of Service condition.
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-9.10.4_p4'
