Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Out-of-bounds write
EUVDB-ID: #VU49344
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-2020-27287
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing project files. A remote attacker can create a specially crafted project file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
MitigationInstall updates from vendor's website.
Vulnerable software versionsCNCSoft-B: 1.0.0.0 - 1.0.0.2

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Out-of-bounds read
EUVDB-ID: #VU49345
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
