4) Buffer overflow
EUVDB-ID: #VU52506
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-22207
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the MS-WSP dissector in Wireshark. A remote attacker can send specially crafted packets over the network or convince the victim to read a malformed packet trace file and consume excessive CPU resources, causing denial of service condition.
Update the affected packages.
