Nagios multiple scripts negative Content-Length header buffer overflow
| nagios-multiple-scripts-bo (26253) |  High Risk |
Description:
Nagios is vulnerable to a buffer overflow, caused by improper bounds checking by multiple CGI scripts. By sending a specially-crafted HTTP request containing a negative Content-Length header, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the system to crash.
Platforms Affected:
- Canonical, Ubuntu 5.04
- Canonical, Ubuntu 5.10
- Debian, Debian Linux 3.1
- Ethan Galstad, Nagios prior to 1.4
- Ethan Galstad, Nagios prior to 2.3
