A Secunia Advisory reports :

The vulnerability is caused due to a boundary error within the redir() function in check_http.c when processing HTTP Location : header information. This can be exploited to cause a buffer overflow by returning an overly long string in the 'Location:' header to a vulnerable system.

The remote host is affected by the vulnerability described in GLSA-200711-11 (Nagios Plugins: Two buffer overflows)

    fabiodds reported a boundary checking error in the 'check_snmp' plugin     when processing SNMP 'GET' replies that could lead to a stack-based     buffer overflow (CVE-2007-5623). Nobuhiro Ban reported a boundary     checking error in the redir() function of the 'check_http' plugin when     processing HTTP 'Location:' header information which might lead to a     buffer overflow (CVE-2007-5198).
  Impact :

    A remote attacker could exploit these vulnerabilities to execute     arbitrary code with the privileges of the user running Nagios or cause     a Denial of Service by (1) sending a specially crafted SNMP 'GET' reply     to the Nagios daemon or (2) sending an overly long string in the     'Location:' header of an HTTP reply. Note that to exploit (2), the     malicious or compromised web server has to be configured in Nagios and     the '-f' (follow) option has to be enabled.
  Workaround :

    There is no known workaround at this time.

Several local/remote vulnerabilities have been discovered in two of the plugins for the Nagios network monitoring and management system.
The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-5198     A buffer overflow has been discovered in the parser for     HTTP Location headers (present in the check_http     module).

  - CVE-2007-5623     A buffer overflow has been discovered in the check_snmp     module.

Nobuhiro Ban discovered that check_http in nagios-plugins did not properly sanitize its input when following redirection requests. A malicious remote web server could cause a denial of service or possibly execute arbitrary code as the user. (CVE-2007-5198)

Aravind Gottipati discovered that sslutils.c in nagios-plugins did not properly reset pointers to NULL. A malicious remote web server could cause a denial of service.

Aravind Gottipati discovered that check_http in nagios-plugins did not properly calculate how much memory to reallocate when following redirection requests. A malicious remote web server could cause a denial of service.
