This signature detects attempts to exploit a known vulnerability against Ethereal, a network analyzer application. Attackers can send a maliciously crafted EIGRP Membership Query response with an overly long prefix length to trigger a buffer overflow and execute arbitrary code.
Ethereal 0.10.3 has been released to address multiple vulnerabilities. These issues include: - Thirteen stack-based buffer overruns in various protocol dissectors (NetFlow, IGAP, EIGRP, PGM, IrDA, BGP, ISUP, and TCAP). - A denial of service that is triggered by a zero length Presentation protocol selector. - Specially crafted RADIUS packets may cause a crash in Ethereal. - Corrupt color filter files may cause a crash in Ethereal. These issues may result in a denial of service or potentially be leveraged to execute arbitrary code in the instance of the buffer overruns.
