Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Infinite loop

EUVDB-ID: #VU21456

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/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-2019-12973

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

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

The vulnerability exists due to excessive iteration in the opj_t1_encode_cblks function of openjp2/t1.c in Open JPEG. A remote attacker can create a specially crafted .bmp file, pass it to the affected application and perform denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

openEuler: 20.03 LTS SP1 - 20.03 LTS SP3

openjpeg2-help: before 2.3.1-9

openjpeg2-debuginfo: before 2.3.1-9

openjpeg2-devel: before 2.3.1-9

openjpeg2-debugsource: before 2.3.1-9

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

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

2) Heap-based buffer overflow

EUVDB-ID: #VU79881

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2021-3575

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 within the sycc420_to_rgb() function in color.c. A remote attacker can pass specially crafted image data to the application, trigger a 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.

3) Improper input validation

EUVDB-ID: #VU11479

Risk: Low

CVSSv4.0: 2 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2018-6616

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a local unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the opj_t1_encode_cblks function, which is defined in the openjp2/t1.c source code file, due to insufficient validation of user-supplied input. A local attacker can submit a specially crafted BMP file and cause the service to crash.

Mitigation

Install updates from vendor's repository.
