If updating to the latest version is not possible for any reason, you can always opt to completely disable the macro features on your office suite, or avoid trusting any documents containing macros. If you're using Linux and the aforementioned versions aren't available on your distribution's package manager yet, you are advised to download the 'deb', or 'rpm' package from the Download center or build LibreOffice from source. Since neither of these two applications offer auto-updating, you should do it manually by downloading the latest version from the respective download centers - LibreOffice, OpenOffice. For OpenOffice, that would be 4.1.10 and later, and for LibreOffice, 7.0.5 or 7.1.1 and later. If you're using either of the open-source office suites, you're advised to upgrade to the latest available version immediately. The same flaw impacts LibreOffice, which is a fork of OpenOffice spawned from the main project over a decade ago, and for their project is tracked as CVE-2021-25635. BleepingComputer reports: The discovery of the flaw, which is tracked as CVE-2021-41832 for OpenOffice, was the work of four researchers at the Ruhr University Bochum. Although the severity of the flaw is classified as moderate, the implications could be dire. Vulnerability in OpenAI's Account Validation Process Allows Unlimited CreditsLibreOffice 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. In December 2022, Checkmarx notified OpenAi of the problem, which had been fixed by March 2023. Researchers also suggested applying normalization before processing the value to make sure the input for both checks are the same. This allowed the attacker to exploit it by appending zeros to the number and inserting non-ASCII bytes to the same old phone number to bypass the first check because this permutation was not identical to the original value. The vulnerability was that the user-supplied phone number was validated by one component using previously registered numbers, and the following phone number was sent to another component that sanitized it before using it for validation purposes. Checkmarx's security experts discovered a technique to circumvent this process by using a catch-all email account with a private domain or any temporary e-mail provider and exploiting a flaw in the phone number verification process.Īttackers will intercept and alter the OpenAI API request in order to circumvent phone number limits, enabling them to submit several variations of the same phone number and yet qualify for the free credit for numerous accounts. Researchers from Checkmarx discovered a flaw in OpenAI's account validation process that lets any user receive an endless amount of free credit from the company by enrolling for services an unlimited number of times using the same phone number.ĭuring the account creation process, OpenAI employs an email and phone number validation mechanism, in which an email address is provided and validated via an activation link, and a validation code is delivered via SMS for phone numbers.
