Vulnerability Note VU#864884
Ethereal contains multiple vulnerabilities in the IGAP protocol dissector
Ethereal contains multiple buffer overflows in the Internet Group Membership Authentication Protocol (IGAP) protocol dissector. These vulnerabilities could allow a remote, unauthenticated attacker to execute arbitrary code.
Ethereal is a network traffic analysis package. It includes the ability to decode packets containing IGAP data. There are two buffer overflow vulnerabilities in the way the IGAP protocol dissector decodes packets containing IGAP data. These vulnerabilities could be exploited by a remote, unauthenticated attacker by sending a specially crafted IGAP packet containing an overly long value for the accountname or message. Exploitation of these vulnerabilities could result in arbitrary code execution.
A remote, unauthenticated attacker could execute arbitrary code on the vulnerable system.
Upgrade to version 0.10.3 or later.
2) Disable the IGAP protocol dissector from the list by unchecking its "Status" checkbox
However, it is strongly encouraged to upgrade to version 0.10.3 or later.
