Background
collectd is a statistics collection and monitoring daemon used for gathering and visualizing system performance data. It is designed to run on various operating systems and supports a wide range of plugins to collect data from different sources. However, collectd versions prior to 5.1.0-3+deb7u2 for Debian 7 Wheezy are vulnerable to a heap overflow and initialization verification issues.
Vulnerability Detail
The heap overflow vulnerability in collectd allows a remote attacker to cause a denial-of-service (DoS) by crashing the application or potentially execute arbitrary code. This vulnerability was discovered by Emilien Gaspar. Additionally, security researchers at Columbia University and the University of Virginia found that collectd failed to verify a return value during initialization, which could lead to the daemon being started without the desired secure settings.
How To Fix
