TITLE

Wireshark 'profinet/packet-dcerpc-pn-io.c' Denial of service vulnerability

Trust: 1.1

sources: IVD: 574b44dd-7862-4fcd-8942-a6046b4023f7 // CNVD: CNVD-2017-16243 // BID: 99187

DESCRIPTION

In Wireshark 2.2.7, PROFINET IO data with a high recursion depth allows remote attackers to cause a denial of service (stack exhaustion) in the dissect_IODWriteReq function in plugins/profinet/packet-dcerpc-pn-io.c. Wireshark (formerly known as Ethereal) is a suite of network packet analysis software developed by the Wireshark team. The function of the software is to intercept network packets and display detailed data for analysis. A security vulnerability exists in the \342\200\230dissect_IODWriteReq\342\200\231 function of the plugins/profinet/packet-dcerpc-pn-io.c file in Wireshark version 2.2.7. Wireshark is prone to a remote denial-of-service vulnerability because it fails to properly handle certain types of packets. Attackers can exploit this issue to crash the affected application, resulting in denial-of-service conditions. Wireshark 2.2.7 is vulnerable; other versions may also be affected
