Re: 2 Issues

1/ The recently released libxml2-python 2.4.19-5.legacy is missing the

2.4.19-6.legacy is in updates-testing now and has the missing modules.


2/ nscd from glibc-2.2.5-44 is vulnerable to DNS cache poisoning. I
don't know how it is when BIND doesn't seem to be affected, but several
times now I've found 'localhost' mapping to an address block assigned to
APNIC. I did a search and a few other people have seen this too. (There was no specific break-in because my firewall kept things sane.)
You can use 'getent' to check ('host' only does DNS; 'getent' does
NSS-lookups): 'getent hosts localhost'. Workaround: Disable cache for
hosts in /etc/nscd.conf or disable nscd (not a good solution if you're
using NIS/LDAP/SQL/etc).

I think that if this were easy to fix Red Hat would have done so when people first complained about it. Personally I've disabled hosts caching on my systems.
