ISC BIND 9 Recursive Server prefetch DoS
Medium Nessus Plugin ID 73945
SynopsisThe remote name server may be affected by a denial of service vulnerability.
DescriptionAccording to its self-reported version number, the remote installation of BIND is affected by a denial of service vulnerability. The issue exists due to an error in the 'prefetch' feature which can cause named to terminate with a 'REQUIRE' assertion failure if it processes queries whose answers have particular attributes.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to BIND version 9.10.0-P1 or later.
Alternatively, in 'named.conf', set the 'prefetch' option to '0'.
