Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Stack-based buffer overflow
EUVDB-ID: #VU56441
Risk: High
CVSSv3.1: 8.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2021-38402
CWE-ID:
CWE-121 - Stack-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 when parsing specific project files. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.

3) Heap-based buffer overflow
EUVDB-ID: #VU56443
Risk: High
CVSSv3.1: 8.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:U/RC:C]
CVE-ID: CVE-2021-38404
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 when parsing specific project files. A remote attacker can pass specially crafted data 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.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.
