Title: Ethereal GIOP Dissector Memory Exhaustion Vulnerability
Severity: MODERATE
Description:
Ethereal is a freely available, open source network traffic analysis tool. It is maintained by the Ethereal Project and is available for most Unix and Linux variants as well as Microsoft Windows operating systems.
The Ethereal GIOP dissector is a mechanism for decoding the General Inter-ORB Protocol (GIOP). A condition exists that may result in exhaustion of available memory. A specially constructed packet may cause allocation of a large amount of memory. Attackers may exploit this vulnerability to cause an exhaustion of available memory.
Successful exploitation may result in Ethereal failing or crashing.
