Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU49185

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/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-2020-27814

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 in lib/openjp2/mqc.c. A remote attacker can pass specially crafted image to the application, 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

Update the affected package openjpeg2 to the latest version.

2) Heap-based buffer overflow

EUVDB-ID: #VU48907

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/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-2020-27823

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 processing PNG images in pngtoimage() function in bin/jp2/convertpng.c. A remote attacker can pass specially crafted file to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.
