Name of the Vulnerable Software and Affected Versions
Wireshark versions 3.6.0 through 3.6.15
Wireshark versions 4.0.0 through 4.0.7
Description
The issue is related to a memory leak in the BT SDP dissector of Wireshark, which can be exploited to cause a denial of service. This can be achieved via packet injection or by using a crafted capture file. The exploitation of this issue may allow a remote attacker to disrupt service.
