CVE-2008-4126 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-4126): 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. different bug than 233217 According to the debian bug, this should be fixed with 2.3.2. As we have 2.3.3 in portage, we should be fine? Confirmed: http://pydns.cvs.sourceforge.net/viewvc/pydns/pydns/DNS/Base.py?view=log#rev1.14 sbriesen, please leave a note on open security bugs when you do a bump, we can't follow every upstream release we have bugs for. Thanks! |
