Sarg useragent() buffer overflow
| sarg-useragent-bo (40970) |  High Risk |
Description:
Sarg is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the useragent() function. By sending an overly long User-Agent header, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
