Ravie Lakshmanan The maintainers of LibreOffice and OpenOffice have shipped security updates to their productivity software to remediate multiple vulnerabilities that could be weaponized by malicious actors to alter documents to make them appear as if they are digitally signed by a trusted source. Although the severity of the flaw is classified as moderate, the implications could be dire. But now (under LO 6.4.7.2), the most locked-down you can get is with 'Very High' security, where 'Only macros from trusted file locations are allowed to run. LibreOffice and OpenOffice have pushed updates to address a vulnerability that makes it possible for an attacker to manipulate documents to appear as signed by a trusted source. This article continues to discuss the security flaw discovered in OpenOffice and LibreOffice that hackers can exploit to fake signed documents as well as the updates released to address it.35 content creators, is your government skit'', Nigerians react as Fintiri unveils 47-man media team - Tribuneģ5-year-old former church youth leader charged with sexually assaulting child - YahooĪ feared Ukrainian female sniper the Russians call 'Punisher' says women can be especially deadly on the battlefield because a male soldier might hesitate to take a shot, but a woman 'never' does - YahooĪ Ukrainian drone spotted a fellow wounded soldier bleeding out on a battlefield. 3m So there's no way to disable macros altogether Seems like you used to be able to do that. It provides a defense against memory safety bugs but does not eliminate other. For LibreOffice 7.0.5 or 7.1.1 and later.Those using at least one of the open-source office suites are recommended to update to the most recent version as quickly as possible. Exploiting the bug would allow an adversary to spoof digital signatures in signed documents as a valid signature. For OpenOffice, that would be 4.1.10 and later, and for LibreOffice, 7.0.5 or 7.1.1 and later. LibreOffice also impacted, but an official patch. The same flaw is tracked as CVE-2021-25635 for LibreOffice, a branch of OpenOffice created more than a decade ago from the main project. LibreOffice, OpenOffice Vulnerability Patched. 0patch releases fix for the recently disclosed remote code execution vulnerability affecting OpenOffice. The flaw, which is tracked as CVE-2021-41832 for OpenOffice, was discovered by four researchers at the Ruhr University Bochum. The method of enabling anyone to sign macro-infested papers and make them appear trustworthy is effective at tricking unsuspecting users into running malicious code. The digital signatures used in document macros are supposed to help the user verify that the document has not been altered and can be trusted. 'Allowing anyone to sign macro-ridden documents themselves, and make them appear as trustworthy, is an excellent way to trick users into running malicious code. The vulnerability is classified as mild in severity, but its exploitation could lead to severe consequences. An Improper Certificate Validation vulnerability in LibreOffice allowed an attacker to self sign an ODF document, with a signature untrusted by the target, then modify it to change the signature algorithm to an invalid (or unknown to LibreOffice) algorithm and LibreOffice would incorrectly present such a signature with an unknown algorithm as a. LibreOffice and OpenOffice have pushed updates to address a vulnerability that makes it possible for an attacker to manipulate documents to appear as signed by a trusted source. OpenOffice and LibreOffice have pushed updates to address a vulnerability that could allow an attacker to spoof signed documents.
