Name of the Vulnerable Software and Affected Versions Wireshark versions 3.2.0 through 3.2.7

Description The issue is related to the GQUIC dissector in Wireshark, which could cause a crash. This was due to an incorrect implementation of offset advancement. The problem can be exploited by a remote attacker to cause a denial of service.
