SB2022032615 - openEuler update for openjpeg2

Description

This security bulletin contains information about 3 vulnerabilities.

1) Infinite loop (CVE-ID: CVE-2019-12973)

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

CVSSv4: 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

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.

2) Heap-based buffer overflow (CVE-ID: CVE-2021-3575)

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

CVSSv4: 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

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.

3) Improper input validation (CVE-ID: CVE-2018-6616)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 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

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.
