Debian DSA-2244-1 : bind9 - incorrect boundary condition
Medium Nessus Plugin ID 55032
SynopsisThe remote Debian host is missing a security-related update.
DescriptionIt was discovered that BIND, an implementation of the DNS protocol, does not correctly process certain large RRSIG record sets in DNSSEC responses. The resulting assertion failure causes the name server process to crash, making name resolution unavailable. (CVE-2011-1910 )
In addition, this update fixes handling of certain signed/unsigned zone combinations when a DLV service is used. Previously, data from certain affected zones could become unavailable from the resolver.
SolutionUpgrade the bind9 packages.
For the oldstable distribution (lenny), this problem has been fixed in version 1:9.6.ESV.R4+dfsg-0+lenny2.
For the stable distribution (squeeze), this problem has been fixed in version 1:9.7.3.dfsg-1~squeeze2.
