CVE-2015-1868 pdns: Label decompression bug in PowerDNS can cause crashes on specific platforms
PowerDNS project has reported the following issue in PowerDNS:
"""
A bug was discovered in our label decompression code, making it possible for
names to refer to themselves, thus causing a loop during decompression. This
loop is capped at a 1000 iterations by a failsafe, making the issue harmless
on most platforms.
However, on specific platforms , the recursion involved in these 1000 steps causes memory
corruption leading to a quick crash, presumably because the default stack is
too small.
We recommend that all users upgrade to a corrected version if at all possible.
Alternatively, if you want to apply a minimal fix to your own tree, it can be
found in two parts:
