Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU61458

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-43304

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in LZ4 compression codec. A remote attacker can pass specially crafted data to the application, trigger heap-based buffer overflow 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.

3) Heap-based buffer overflow

EUVDB-ID: #VU61460

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-42387

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error in the LZ4 compression codec when parsing queries. A remote attacker can pass specially crafted data to the application, trigger heap-based buffer overflow and gain access to sensitive information or perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's website.
