Description Mark J. Cox 2003-03-17 04:34:52 EST
Description of problem:

Timing attack on RSA decryption because RSA blinding isn't
used in all applications (mod_ssl etc)

Version-Release number of selected component (if applicable):

This affects most applications that link to OpenSSL

How reproducible:

In order to exploit this issue you need to be local to the machine or be on a
network that enables you to reliably observe sub 1ms timing differences.  

Additional info:


This is CAN-2003-0147

A patch is being prepared by the OpenSSL team that enabled RSA blinding by default.
