Somebody knows ETA of a fix coming out ?

For most people, this will be the answer:

The binaries from Bitcoin.org are not effected, not on any operating system.

Virtually all users on Windows and OSX are not impacted, because virtually all of them use provided binaries. The only way you are possibly effected on those platforms is if you built the software for yourself and if you update OpenSSL.

If you did compile your own software, then you can run "make check" in the source tree to see if you're affected. If all tests pass, you're not affected. You might want to check again after you update your system's OpenSSL.

Those who compile their own software can fix their software by applying a patch. The required changes are available on Github; e.g. here for the 0.9 branch.

I created a version of the 0.9 sources that's nearly identical to the official 0.9.3 source code release for Linux, but with the fix applied:
https://github.com/cornwarecjp/bitcoin/tree/b146f97935d6c17927406ea549409d232eb7ce3c

I wouldn't recommend doing development on that branch(*), but since it's nearly identical to the official release source code, it should be OK for compiling your own Bitcoin binary. Check for yourself with a diff tool what the differences are with the 0.9.3 sources and make sure you agree. In Linux desktops, you can e.g. use the "Meld" program for this, and use it to compare directories.

(*) The reason being that it's become quite different from development branches, which might make it more difficult to merge things.
