Details
A remote DoS (denial of service) attack is possible with bind versions
prior to 8.2.2_P7.
2000-11-12: Added bind-devel, bind-utils packages to package list.
A bug in bind 8.2.2_P5 allows for a denial of service attack.
If named is open to zone transfers and recursive resolving, it will crash
after a ZXFR for the authoritative zone and a query of a remote hostname.
Solution
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
Disabling zone transfers to non-trusted hosts by adding
allow-transfer { trusted-hosts; };
to /etc/named.conf prevents the exploit from working on older releases,
however, this does not fix the problem.
