Description Jan Lieskovsky 2010-10-06 17:43:26 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2010-3762 to
the following vulnerability:

ISC BIND before 9.7.2-P2, when DNSSEC validation is enabled, does not
properly handle certain bad signatures if multiple trust anchors exist
for a single zone, which allows remote attackers to cause a denial of
service (daemon crash) via a DNS query.

Comment 1 Jan Lieskovsky 2010-10-07 13:34:04 UTC

This issue did NOT affect the versions of the bind package, as shipped
with Red Hat Enterprise Linux 3 and 4, as those versions implement the
Domain Name System Security Extensions (DNSSEC) in different way.

This issue affects the version of the bind package, as shipped with
Red Hat Enterprise Linux 5.

--

This issue does NOT affect the versions of the bind package, as shipped
with Fedora release of 12 and 13 (as relevant bind packages are already
updated).

Comment 6 Jan Lieskovsky 2013-08-07 09:50:29 UTC
