Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU46753
Risk: High
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-6146
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 in the rendering functionality when drawing the contents of a page and selecting the stroke color from an “ICCBased” colorspace. A remote attacker can trick a victim to load a specially crafted document, 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.
