Signature Detail

APP: Ethereal UDP Netflow Dissector Buffer Overflow

This signature detects attempts to exploit a known vulnerability against the NetFlow dissector in Ethereal. Attackers can send maliciously crafted packets to the vulnerable dissectors to possibly execute arbitrary code on the host running Ethereal.

Extended Description

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.
