ifenslave 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.
|
|
|
|
It is possible for a local attacker to seize control of the vulnerable application and have malicious arbitrary code executed in the context of ifenslave. ifenslave is not installed setUID or setGID by default.
|
|
|
|
It should be noted that although this vulnerability has been reported to affect ifenslave version 0.07 previous versions might also be affected.
