Description Vincent Danen 2012-07-19 22:40:11 UTC 
Florian Weimer of the Red Hat Product Security Team discovered two memory leaks in libpcp that can be abused by an unauthenticated remote attacker to crash pmcd (the PCP (Performance Co-Pilot) performance metrics collector daemon) or to consume enough memory to trigger the OOM killer, which may have impact on other processes.
Comment 1 Vincent Danen 2012-07-19 22:41:43 UTC 
This CVE comprises of two flaws:

bug #841298  pmcd leaks memory in DoFetch error path
bug #841319  In-band signaling in __pmGetPDU causes pmcd memory leak

Both bugs have respective upstream patches which addresses them.
