OpenSSL < 0.9.8k Signature Repudiation

low Nessus Plugin ID 17764


The remote server is affected by a signature repudiation vulnerability.


According to its banner, the remote server is running a version of OpenSSL that is earlier than 0.9.8k. As such, it may allow a valid sign to generate invalid signatures which would appear valid and could be repudiated later.

This only affects CMS users. CMS appeared in OpenSSL 0.9.8h.


Upgrade to OpenSSL 0.9.8k or later.
