Title: Nagios Remote Content-Length Integer Overflow Vulnerability
Severity: HIGH
Description:
Nagios is an open-source application designed to monitor networks and services for service interruptions and to notify administrators when various events occur.
Nagios is susceptible to a remote buffer-overflow vulnerability. The application fails to properly ensure that user-supplied input doesn't overflow integer values. This may result in user-supplied data being copied past the end of a memory buffer.
This issue presents itself when attackers supply 'Content-Length' HTTP request headers to various unspecified CGI applications.
This issue allows remote attackers to execute arbitrary machine code in the context of hosting webservers.
Nagios versions prior to 2.3.1 are vulnerable to this issue.
This issue is very similar to BID 17879 (Nagios Remote Negative Content-Length Buffer Overflow Vulnerability), but is a separate issue.
