Description |
34 |
=========== |
35 |
|
36 |
When Pavuk connects to a web server and the server sends back the HTTP |
37 |
status code 305 (Use Proxy), Pavuk copies data from the HTTP Location |
38 |
header in an unsafe manner. |

Impact |
41 |
====== |
42 |
|
43 |
An attacker could cause a stack-based buffer overflow which could lead |
44 |
to arbitrary code execution with the rights of the user running Pavuk. |
45 |
|
46 |
