Message | EXPLOIT IGMP IGAP account overflow attempt |
Summary | This event is generated when an attempt is made to exploit a buffer overflow associated with the Ethereal decode of the Internet Group membership Authentication Protocol (IGAP).
|
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 IGAP packet is decoded using Ethereal or tethereal. This may permit the execution of arbitrary code with root or LOCAL_SYSTEM privilege. The buffer overflow occurs when a larger than expected User Account Size value is discovered in the IGAP payload.
|
Affected Systems | Any host running Ethereal/tethereal versions 0.10.0 - 0.10.2.
|
Attack Scenarios | An attacker can create and send a malformed IGAP packet, and if decoded by a vulnerable version of Ethereal/tethereal, 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.
