Technical details
A buffer overflow vulnerability exists in NCSA WebServer versions 1.4.1 and prior. The flaw is reachable over the network without authentication, allowing a remote attacker to execute arbitrary code or gain a shell on the affected host. This is a classic stack-based or heap-based overflow resulting from improper bounds checking on input. Successful exploitation grants the attacker full control over the server process, typically with the privileges of the user running the web server daemon.
Affected products
