I just wanted to post my view and the next steps for a vulnerability
that was recently discovered in glibc.
IPFire does not directly connect to the Internet. All DNS queries go
through a DNS proxy (dnsmasq) first. dnsmasq limits the maximum reply
size to 1280 bytes. To exploit the vulnerability, packets of at least
2048 bytes are required.
So dnsmasq protects IPFire and the systems behind it. This is however
not a reason to not patch the vulnerability. It is still a rather
serious vulnerability that makes *all* software that resolves names
Arne has already branched a new Core Update which will be available for
