CVE-2020-13164: Debian Linux

High severity, CVSS 7.5. EPSS: 3% chance of exploitation in the next 30 days.

In Wireshark 3.2.0 to 3.2.3, 3.0.0 to 3.0.10, and 2.6.0 to 2.6.16, the NFS dissector could crash. This was addressed in epan/dissectors/packet-nfs.c by preventing excessive recursion, such as for a cycle in the directory graph on a filesystem.

• Fedoraproject Fedora: version 31 only; version 32 only
• Opensuse Leap: version 15.1 only; version 15.2 only
