NVD Description

Note: Versions mentioned in the description apply only to the upstream rrdtool package and not the rrdtool package as distributed by Ubuntu.

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.
