A flaw was found in rrdcached, a component of rrdtool. A local attacker with access to a rrdcached socket can exploit a stack-based buffer overflow by sending an oversized CREATE request. This vulnerability can lead to a denial of service by crashing the daemon or potentially allow for arbitrary code execution, impacting the integrity and confidentiality of data.

Thomas Pollet (thomas.pollet) reports:

Also, the rrdtool python module crashes on format string exploit $ python -c "import rrdtool rrdtool.graph('/tmp/out.png','-f','%n%n')" Segmentation fault

this module is used by zenoss to create graphs (zenoss users are able to pass arguments to rrdtool).
