Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Insecure DLL loading

EUVDB-ID: #VU92102

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2024-33871

CWE-ID: CWE-427 - Uncontrolled Search Path Element

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to the "Driver" parameter for the "opvp"/"oprp" device specifies the name of a dynamic library and allows any library to be loaded. A remote attacker can pass a specially crafted document to the application and execute arbitrary library on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise the affected system.

Mitigation

Install updates from vendor's website.
