Description

A Buffer Overflow in Wireshark before 4.2.0 allows a remote attacker to cause a denial of service via the wsutil/to_str.c, and format_fractional_part_nsecs 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.
