| GEN:SID | 1:2464 |
| 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. |
