SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200903-14 (BIND: Incorrect signature verification)
BIND does not properly check the return value from the OpenSSL functions to verify DSA (CVE-2009-0025) and RSA (CVE-2009-0265) certificates.
A remote attacker could bypass validation of the certificate chain to spoof DNSSEC-authenticated records.
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-9.4.3_p1'
