EUVDB-ID: #VU50148

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2021-22173

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak within USB HID dissector. A remote attacker can force the application to leak memory and perform denial of service attack.

Mitigation

Update the affected packages.
net-analyzer/wireshark to version: 3.4.6

Vulnerable software versions

Gentoo Linux: All versions
