1) Information disclosure
EUVDB-ID: #VU82941
Risk: Low
CVSSv3.1: 2.7 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-5868
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in the aggregate function calls when handling "unknown"-type arguments. A remote user can read parts of system memory.
Install updates from vendor's website.

2) Integer overflow
EUVDB-ID: #VU82942
Risk: High
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-5869
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in array modification. A remote user can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
