Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Use of out-of-range pointer offset

EUVDB-ID: #VU60777

Risk: Low

CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

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

CVSSv4.0: 0.2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

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

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

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.

4) Heap-based buffer overflow

EUVDB-ID: #VU60776

Risk: High

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2022-0572

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 when repeatedly using :retab. A remote attacker can trick the victim to open a specially crafted file, 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 repository.
