Synopsis

Nagios is vulnerable to a buffer overflow which may lead to remote execution of arbitrary code.

Background

Nagios is an open source host, service and network monitoring program.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-analyzer/nagios-core	< 1.4.1	>= 1.4.1	All supported architectures

Description

Sebastian Krahmer of the SuSE security team discovered a buffer overflow vulnerability in the handling of a negative HTTP Content-Length header.

Impact

A buffer overflow in Nagios CGI scripts under certain web servers allows remote attackers to execute arbitrary code via a negative content length HTTP header.

Workaround

There is no known workaround at this time.

Resolution
