Description Tomas Mraz 2007-08-02 06:20:01 EDT
+++ This bug was initially created as a clone of Bug #245732 +++

The OpenSSL team made the following commit publically to the 0.9.8 head:

This is a possible weakness in OpenSSL which could allow a local user in certain
circumstances to divulge information about private keys being used.   For
example if a server has a SSL web server on it, a local unprivileged user may be
able to get hold of the key.  

I'm not sure in practice how possible this would be; it would rely on a system
that isn't doing much else that could interfere with some spy process designed
to figure out this information (and probably won't be possible if you have a
server handling a lot of traffic, has more than one key, lots of local
processes, and so on).

It's similar to previous issues and is rated severity=moderate

I'm not sure if the OpenSSL team plan to upgrade older versions of OpenSSL or
when this will be announced publicly.  Please treat as embargoed for now.

Because this change has not been tested in a full upstream OpenSSL release there
is some risk that it may introduce unexpected side-effects.  Given this issue is
not serious, our current plan is as follows:

- To include the backported fix in an OpenSSL update ready for RHEL 4.6.   This
will get testing via beta and give time for more extensive internal testing
- To release an async update for OpenSSL for other RHEL platforms at the same
time as RHEL4.6 is released
