Message | EXPLOIT EIGRP prefix length overflow attempt |
Summary | This event is generated when an attempt is made to exploit a buffer overflow associated with the Ethereal decode of the Enhanced Interior Gateway Routing Protocol (EIGRP).
|
Impact | A successful attack may allow the execution of arbitrary code as root or LOCAL_SYSTEM privilege on a vulnerable host.
|
Detailed Information | There is a vulnerability associated with particular versions of Ethereal that may cause a buffer overflow when a malformed EIGRP packet is decoded. This may permit the execution of arbitrary code with root or LOCAL_SYSTEM privilege. The buffer overflow occurs when a larger than expected packet length value is discovered in the EIGRP payload.
|
Affected Systems | Any host running Ethereal versions 0.8.14 through 0.10.2.
|
Attack Scenarios | An attacker can create and send a malformed EIGRP packet, and if decoded by a vulnerable version of Ethereal, can cause a buffer overflow and the subsequent execution of arbitrary code.
|
Ease of Attack | Simple. Exploit code is available.
|
Corrective Action | Update to version 0.10.3 of Ethereal.
