Description Florian Weimer 2012-07-18 09:54:14 EDT
This is very similar to the __pmDecodeInstanceReq overflow (bug 841240).  buflen needs to be checked against the PDU size, and negative values need to be rejected.

This is not directly exposed through pmcd.

This looks okay, with the same caveat as in bug 841240.
