CVE-ID: CVE-2019-9848

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation in LibreLogo component, bundled with LibreOffice application. A remote attacker can create a specially crafted document, trick the victim into opening it and execute arbitrary python code on the target system without displaying any warnings.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected packages.
