Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Use of out-of-range pointer offset

EUVDB-ID: #VU60777

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-0554

CWE-ID: CWE-823 - Use of Out-of-range Pointer Offset

Exploit availability: No

Description

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a boundary error when reading files. A remote attacker can trick the victim to open a specially crafted file and crash the application.

Mitigation

Install updates from vendor's repository.

2) Out-of-bounds read

EUVDB-ID: #VU60787

Risk: Low

CVSSv3.1: 2.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-0319

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.

Mitigation

Install updates from vendor's repository.

3) Stack-based buffer overflow

EUVDB-ID: #VU60775

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-2022-0629

CWE-ID: CWE-121 - Stack-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 when using many composing characters in error message. A remote unauthenticated attacker can trick the victim to open a specially crafted file, trigger a stack-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 repository.
