Description

The version of IBM HTTP Server running on the remote host is affected by a side channel information disclosure. GSKit V7 discloses side channel information via discrepancies between valid and invalid PKCS#1 padding.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
