A vulnerability in BIND might allow remote attackers to cause a Denial of Service condition.
|Package||net-dns/bind on all architectures|
|Affected versions||< 9.10.4_p4|
|Unaffected versions||>= 9.10.4_p4|
BIND (Berkeley Internet Name Domain) is a Name Server.
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.
All BIND users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-dns/bind-9.10.4_p4"
