Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU50081

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-22305

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists due to a module does not verify some input when dealing with messages. A local attacker can trigger memory corruption and cause a denial of service on the target system.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

Huawei Mate 30: 10.1.0.126(C00E125R5P3)

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Buffer overflow

EUVDB-ID: #VU50087

Risk: Low

CVSSv3.1: 5.8 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-22301

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a local user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error. A local administrator can trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install updates from vendor's website.
