Security Fixes 9.4-ESV-R4 * Adding a NO DATA signed negative response to cache failed to clear any matching RRSIG records already in cache. A subsequent lookup of the cached NO DATA entry could crash named (INSIST) when the unexpected RRSIG was also returned with the NO DATA cache entry. [RT #22288] [CVE-2010-3613] [VU#706148] * BIND, acting as a DNSSEC validator, was determining if the NS RRset is insecure based on a value that could mean either that the RRset is actually insecure or that there wasn't a matching key for the RRSIG in the DNSKEY RRset when resuming from validating the DNSKEY RRset. This can happen when in the middle of a DNSKEY algorithm rollover, when two different algorithms were used to sign a zone but only the new set of keys are in the zone DNSKEY RRset. [RT #22309] [CVE-2010-3614] [VU#837744] Bug Fixes 9.4-ESV-R4 * isc_print_vsnprintf() failed to check if there was space available in the buffer when adding a left justified character with a non zero width, (e.g. "%-1c"). [RT #22270] * win32: add more dependencies to BINDBuild.dsw. [RT #22062] Thank You Thank you to everyone who assisted us in making this release possible.
