CVE-2017-6467
In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a Netscaler file parser infinite loop, triggered by a malformed capture file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.59%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
