Ghost glibc vulnerability and CloudStack
There’s a new vulnerability out in most Linux distributions that has potential to be fairly severe. As it affects most Linux distributions, we’re putting mitigation steps out immediately at [1].
This affects many Linux distributions, so please review management servers, databases, storage systems, etc.
An updated SSVM template is being QAed, once released the post will be updated with links and we’ll mention here as well.

Is apache httpd configured to disable hostname lookups (for access/error
log)?
If not it is easy to trigger a reverse dns lookup just by connecting to it
(which various scanners / exploiters do regularily).
That's not to say that httpd is vulnerable though, has the httpd project
given any info about their codebase?

The only way a user can directly reach SSVM is by using download template.
To be able to get SSVM do a DNS lookup for some host as desired by the attacker, by using download template functionality looks far fetched.

As far as the SSVM is concerned, can this be exploited remotely?
