Description

This security bulletin contains information about 4 secuirty vulnerabilities.

1) Buffer overflow (CVE-ID: CVE-2021-22305)

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.

2) Buffer overflow (CVE-ID: CVE-2021-22301)

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.

3) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2021-22307)

The vulnerability allows a local attacker to compromise the target system.

The vulnerability exists due to a weak algorithm issue. A local attacker can affect the integrity of certain module.

4) Out-of-bounds read (CVE-ID: CVE-2021-22306)

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

The vulnerability exists due to a boundary condition. An attacker with physical access can trigger out-of-bounds read error and cause a denial of service condition on the system.
