Huawei EulerOS: Security Advisory for libreoffice (EulerOS-SA-2021-1687)

Published: 2021-03-24 06:54:26
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:N/C:N/I:P/A:N

Summary:
The remote host is missing an update for the Huawei EulerOS 'libreoffice' Linux Distribution Package(s) announced via the EulerOS-SA-2021-1687 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
LibreOffice has a 'stealth mode' in which only documents from locations deemed 'trusted' are allowed to retrieve remote resources. This mode is not the default mode, but can be enabled by users who want to disable LibreOffice's ability to include remote resources within a document. A flaw existed where bullet graphics were omitted from this protection prior to version 6.2.5. This issue affects: Document Foundation LibreOffice versions prior to 6.2.5.(CVE-2019-9849) ODF documents can contain forms to be filled out by the user. Similar to HTML forms, the contained form data can be submitted to a URI, for example, to an external web server. To create submittable forms, ODF implements the XForms W3C standard, which allows data to be submitted without the need for macros or other active scripting Prior to version 6.4.4 LibreOffice allowed forms to be submitted to any URI, including file: URIs, enabling form submissions to overwrite local files. User-interaction is required to submit the form, but to avoid the possibility of malicious documents engineered to maximize the possibility of inadvertent user submission this feature has now been limited to http[s] URIs, removing the possibility to overwrite local files. This issue affects: The Document Foundation LibreOffice versions prior to 6.4.4.(CVE-2020-12803)

Affected Versions:
'libreoffice' Linux Distribution Package(s) on Huawei EulerOS V2.0SP5.

Recommendations:
Please install the updated Linux Distribution Package(s).

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
