Description

A buffer overflow in Wireshark before 4.2.0 allows a remote attacker to cause a denial of service via the pan/addr_resolv.c, and ws_manuf_lookup_str(), size components. NOTE: this is disputed by the vendor because neither release 4.2.0 nor any other release was affected.

Affected products

• Fedoraproject Fedora: 40
• Wireshark Foundation Wireshark: before 4.2.0 — fixed in 4.2.0

How to fix

Upgrade to a fixed version: Wireshark Foundation Wireshark 4.2.0. Check the vendor advisory for mitigations.
