Detailsinfo

A vulnerability was found in Ethereal (Packet Analyzer Software). It has been classified as problematic. This affects an unknown functionality of the component GIOP Dissector. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

Unknown vulnerability in the (1) GIOP dissector, (2) WBXML, or (3) CAMEL dissector in Ethereal 0.8.20 through 0.10.11 allows remote attackers to cause a denial of service (application crash) via certain packets that cause a null pointer dereference.

The bug was discovered 07/26/2005. The weakness was released 07/26/2005 by Steve Grubb (iDefense) with iDEFENSE (Website). It is possible to read the advisory at gentoo.org.
