Hello John,
What i am asking is if i can apply this patch manually or something
like this without making any upgrade of Asterisk, has anyone done this
before?
I can't answer that question.
Or i have to upgrade my Asterisk versions...i don't really want to do
this...
Why not? MANY fixes have been included in the upgrades.
Improved security at the least. There are 10-15 versions between where
you are operating and what is current

Thanks in Advance!

Hasn't this been fixed in later versions?
1.4.37 is current, or at least it was in the last few days.
Upgrading with no reason isn't suggested, but in this case you
have a good reason, and if you dig deep enough you may find the
fix is already in place.

Hello Asterisk community,
We are having some problems with crashes in Asterisk, my asterisk
versions are 1.4.24.1 and 1.4.23.2. I have found this:
"~/work/asterisk-branch-1.4$ svn log -c 260345

Fix potential crash from race condition due to accessing
channel data
without the channel locked.
In res_musiconhold.c, there are several places where a channel's
stream's existence is checked prior to calling ast_closestream
on it. The issue
here is that in several cases, the channel was not locked
while checking the
stream. The result was that if two threads checked the state
of the channel's
stream at approximately the same time, then there could be a
situation where
both threads attempt to call ast_closestream on the channel's
stream. The result
here is that the refcount for the stream would go below 0,
resulting in a crash.
I have added proper channel locking to res_musiconhold.c to
ensure that
we do not try to check chan->stream without the channel locked. A
Digium customer has been using this patch for several weeks
and has not
had any crashes since applying the patch.
