Updated 14.10.2022
Assigned CVE-ID number to vulnerabilities #2,4,6
1) Out-of-bounds read
EUVDB-ID: #VU68093
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]
CVE-ID: N/A
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted XMT file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.

2) Stack-based buffer overflow
EUVDB-ID: #VU68094
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-2022-42901
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. A remote unauthenticated attacker can trick a victim to open a specially crafted XMT file, 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.
