CVE-2017-13767
In Wireshark 2.4.0, 2.2.0 to 2.2.8, and 2.0.0 to 2.0.14, the MSDP dissector could go into an infinite loop.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
