OFFSystem HTTP headers buffer overflow

offsystem-httpheaders-bo (43187)

High Risk

Description:

OFFSystem is vulnerable to a buffer overflow, caused by improper bounds checking when handling HTTP headers. By sending a specially-crafted HTTP request with a malformed HTTP header, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
