Title:	Debian: Security Advisory (DLA-3368-1)
Summary:	The remote host is missing an update for the Debian 'libreoffice' package(s) announced via the DLA-3368-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'libreoffice' package(s) announced via the DLA-3368-1 advisory. Vulnerability Insight: Multiple vulnerabilities were found in LibreOffice an office productivity software suite, leading to arbitrary script execution, improper certificate validation, and weak encryption of password storage in the user's configuration database. CVE-2021-25636 Only use X509Data 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 contain both X509Data and KeyValue children of the KeyInfo tag, which when opened caused LibreOffice to verify using the KeyValue but to report verification with the unrelated X509Data value. CVE-2022-3140 Insufficient validation of vnd.libreoffice.command URI schemes. LibreOffice supports Office URI Schemes to enable browser integration of LibreOffice with MS SharePoint server. An additional scheme vnd.libreoffice.command specific to LibreOffice was added. In the affected versions of LibreOffice links using that scheme could be constructed to call internal macros with arbitrary arguments. Which when clicked on, or activated by document events, could result in arbitrary script execution without warning. CVE-2022-26305 Compare authors using Thumbprint An Improper Certificate Validation vulnerability in LibreOffice existed where determining if a macro was signed by a trusted author was done by only matching the serial number and issuer string of the used certificate with that of a trusted certificate. This is not sufficient to verify that the macro was actually signed with the certificate. An adversary could therefore create an arbitrary certificate with a serial number and an issuer string identical to a trusted certificate which LibreOffice would present as belonging to the trusted author, potentially leading to the user to execute arbitrary code contained in macros improperly trusted. CVE-2022-26306 LibreOffice supports the storage of passwords for web connections in the user's configuration database. The stored passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice existed where the required initialization vector for encryption was always the same which weakens the security of the encryption making them vulnerable if an attacker has access to the user's configuration data CVE-2022-26307 Add Initialization Vectors to password storage. LibreOffice supports the storage of passwords for web connections in the user's configuration database. The stored passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice existed where master key was poorly encoded resulting in weakening its entropy from 128 to 43 ... [Please see the references for more information on the vulnerabilities] Affected Software/OS: 'libreoffice' package(s) on Debian 10. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:P/A:N
