"comment": "This paper describes a possible side-channel attack that hasn\u2019t been proven outside of a lab environment. In reality many factors would make this harder to exploit. If exploited, a local user could obtain RSA private keys (for example for web sites being run on the server). We have rated this as affecting Red Hat products with moderate security severity. Although the OpenSSL team have produced a patch for this issue, it is non-trivial and will require more testing before we can deploy it in a future update. Our current plan is as follows:\n\n- To include a backported fix in an OpenSSL update as part of Enterprise Linux 4.6. This will get testing via beta and give time for more extensive internal and upstream testing\n- To release an update for OpenSSL for other platforms at the same time as 4.6 is released\n http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=CVE-2007-3108\n",
