For those running Exim <= 4.69 (the default Debian
MTA), you should be
aware there is an exploit for remote *root* code execution in the wild.
I don't know whether to be worried or not...
If you run Debian and have not updated in the last 2-3 days then yes
you need to worry (and may already have been exploited).
dpkg-query -l exim
exim 3.36-18.2 An obsolete MTA (Mail Transport
Agent), replaced by exim4
This is a virtual package designed to transition people to exim4
from years ago. Try again with exim4. You want 4.69-9+lenny1, if
we're talking about Debian lenny.
Is there anyway to confirm whether or not this exploit is still
exposed in the 3.36-18.2 package...someone on another list suggested
it was not...
(...not that it might not have other, different exploits or a stack of
other good reasons why it should be upgraded)
