Old versions of Domino and Notes client susceptible to a specific Denial Of Service attacks

This is a few days old but I missed it at the time and haven’t seen it elsewhere. HCL have published some security alerts around Denial of Service (DDOS) attacks.

The first effects versions of Domino previous to previous to releases 9.0.1 FP10 IF6, 10.0.1 FP5 and 11.0.1.

The second effects version of Domino previous to release 11.

Yet another reason why it is always good to stay current on your releases.

There is an additional alert that effects 9, 10 and early 11 versions of the Notes client.

If you require any advice on security or upgrading, please contact us and we’d be happy to assist.
