Details

Description

Multiple dissectors could go into large infinite loops. All ASN.1 BER dissectors, along with the DICOM, DMP, LLTD, OpenFlow, RELOAD, RPCoRDMA, RPKI-Router, S7COMM, SCCP, Thread, Thrift, USB, and WCCP dissectors were susceptible.

Impact

It may be possible to make Wireshark consume excessive CPU resources by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.

Resolution

Upgrade to Wireshark 2.4.5, 2.2.13 or later.
