The DVB-S2-BB dissector could go into an infinite loop. It may be possible to make Wireshark consume excessive CPU resources by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. Affected versions: 3.4.0 to 3.4.5, fixed versions: 3.4.6 References: https://github.com/wireshark/wireshark/commit/0137c24d60934f131b25506a88c9464e4dc827de https://github.com/wireshark/wireshark/commit/0d8be1fb797b3d65f1c2c204da76af8e8de6d3cc https://www.wireshark.org/security/wnpa-sec-2021-05.html
