GKrellMd has been reported prone to a remote buffer overflow vulnerability, arbitrary code execution is possible.
|
|
|
|
The issue presents itself due to a lack of sufficient bounds checking performed on network-based data. If data exceeding the maximum reserved memory buffer size is received arbitrary memory may be corrupted.
|
|
|
|
A remote attacker may ultimately exploit this issue remotely to seize control of the affected daemon and execute arbitrary code.
|
|
|
|
This vulnerability has been reported to affect Gkrellm 2.1.13.
