Detailsinfo

A vulnerability classified as problematic was found in Wireshark (Packet Analyzer Software). Affected by this vulnerability is the function dissect_pft of the file packet-dcp-etsi.c of the component DCP ETSI Dissector. The manipulation as part of a Fragment Length leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect availability. The summary by CVE is:

The dissect_pft function in epan/dissectors/packet-dcp-etsi.c in the DCP ETSI dissector in Wireshark 1.6.x before 1.6.16, 1.8.x before 1.8.8, and 1.10.0 does not validate a certain fragment length value, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The weakness was presented 05/25/2013 by Buildbot Builder as not defined advisory (Website). The advisory is shared at wireshark.org. This vulnerability is known as CVE-2013-4083 since 06/09/2013.
