Title

LibreOffice信任管理问题漏洞（CNVD-2022-55627）

Description

LibreOffice是一套可与其他主要办公室软体相容的套件，可在各种平台上执行。 LibreOffice存在信任管理问题漏洞。攻击者可利用该漏洞通过操纵文档中的documentsignatures.xml或macrosignatures.xml流来组合多个证书数据，从而创建数字签名的ODF文档，打开时，会导致LibreOffice显示一个有效签名的指示器，但其内容与显示的签名无关。

CVE-2021-25633 (GCVE-0-2021-25633)

Vulnerability from cvelistv5 – Published: 2021-10-11 16:43 – Updated: 2024-09-16 18:28

Title

Content Manipulation with Double Certificate Attack

Summary

LibreOffice supports digital signatures of ODF documents and macros within documents, presenting visual aids that no alteration of the document occurred since the last signing and that the signature is valid. An Improper Certificate Validation vulnerability in LibreOffice allowed an attacker to create a digitally signed ODF document, by manipulating the documentsignatures.xml or macrosignatures.xml stream within the document to combine multiple certificate data, which when opened caused LibreOffice to display a validly signed indicator but whose content was unrelated to the signature shown. This issue affects: The Document Foundation LibreOffice 7-0 versions prior to 7.0.6; 7-1 versions prior to 7.1.2.

Severity

No CVSS data available.

CWE
