Debian Security Advisory
DLA-575-1 collectd -- LTS security update
- Date Reported:
- 30 Jul 2016
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 832507, Bug 832577.
In Mitre's CVE dictionary: CVE-2016-6254.
- More information:
Emilien Gaspar discovered that collectd, a statistics collection and monitoring daemon, incorrectly processed incoming network packets. This resulted in a heap overflow, allowing a remote attacker to either cause a DoS via application crash, or potentially execute arbitrary code.
Additionally, security researchers at Columbia University and the University of Virginia discovered that collectd failed to verify a return value during initialization. This meant the daemon could sometimes be started without the desired, secure settings.
For Debian 7
Wheezy, these problems have been fixed in version 5.1.0-3+deb7u1.
We recommend that you upgrade your collectd packages.
