Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Infinite loop
EUVDB-ID: #VU21456
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-2019-12973
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe 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.
Install updates from vendor's repository.

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
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-3575
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe 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.

3) Improper input validation
EUVDB-ID: #VU11479
Risk: Low
CVSSv3.1: 3.6 [CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-6616
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe 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.
