Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Infinite loop

EUVDB-ID: #VU60525

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-2022-0586

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in RTMPT dissector. A remote attacker can send specially crafted packets over the network, consume all available system resources and cause denial of service conditions.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

Wireshark: 3.4.0 - 3.6.1

2) Infinite loop

EUVDB-ID: #VU60524

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-2022-0585

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to large loops in multiple dissectors including AMP, ATN-ULCS and possibly other ASN.1 PER dissectors, BP, GDSDB, OpenFlow v5, P_MUL, SoulSeek, TDS, WBXML, WSP and possibly other WAP dissectors, and ZigBee ZCL. A remote attacker can send specially crafted packets over the network, consume all available system resources and cause denial of service conditions.

Mitigation

Install updates from vendor's website.
