Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) 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

Description

The 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.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

openEuler: 20.03 LTS SP1 - 20.03 LTS SP3

wireshark-help: before 2.6.2-21

wireshark-debuginfo: before 2.6.2-21

wireshark-debugsource: before 2.6.2-21

wireshark-devel: before 2.6.2-21
