Ganglia: Execution of arbitrary code

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
sys-cluster/ganglia	< 3.1.1-r2	>= 3.1.1-r2	All supported architectures

Related bugreports: #255366

A buffer-overflow in Ganglia's gmetad might lead to the execution of arbitrary code.

2. Impact Information

Ganglia is a scalable distributed monitoring system for clusters and grids.

Spike Spiegel reported a stack-based buffer overflow in the process_path() function when processing overly long pathnames in gmetad/server.c.

A remote attacker could send a specially crafted request to the gmetad service leading to the execution of arbitrary code or a Denial of Service.

3. Resolution Information

There is no known workaround at this time.

All Ganglia users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-cluster/ganglia-3.1.1-r2"
