Description Josh Bressers 2008-09-18 19:37:31 UTC

PyDNS (aka python-dns) before 2.3.1-5 in Debian GNU/Linux does not use
random source ports for DNS requests and does not use random
transaction IDs for DNS retries, which makes it easier for remote
attackers to spoof DNS responses, a different vulnerability than
CVE-2008-1447. NOTE: this vulnerability exists because of an
incomplete fix for CVE-2008-4099.

Comment 1 Tomas Hoger 2008-09-29 14:46:58 UTC

We currently do not ship any PyDNS version affected by the issue described in this CVE - there's either 2.3.0 in F8/F9 that is affected by the original issue (CVE-2008-4099), or 2.3.3 in Rawhide, which contains complete upstream fix.

Hence I'm closing this bug, only original issue needs to be tracked.
