Polymorph for Linux has been reported prone to a buffer overflow vulnerability.
|
|
|
|
The issue is reportedly due to a lack of sufficient bounds checking performed on user-supplied data before it is copied into an internal memory space.
|
|
|
|
Specifically, excessive data passed as the 'file' argument to the vulnerable Polymorph executable, when copied into internal memory, may overrun the boundary of the assigned buffer and corrupt adjacent memory.
|
|
|
|
This vulnerability may be exploited to execute arbitrary attacker-supplied code.
|
|
|
|
It should be noted that although this vulnerability has been reported to affect Polymorph version 0.4.0 previous versions might also be affected.
