Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Memory leak

EUVDB-ID: #VU26456

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-5861

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 to the Traffic Management Microkernel (TMM) process may produce a core file in some cases when Ram Cache incorrectly optimizes stored data. A remote attacker can cause a denial of service condition on the target system.

Mitigation

Install updates from vendor's website.

4) Input validation error

EUVDB-ID: #VU26460

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2020-5859

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send specially crafted HTTP/3 messages, cause the Traffic Management Microkernel (TMM) to produce a core file and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's website.
