Привет, из-за последних событий решил поделиться материалами по собеседованиям в зарубежные компании, которые сам собирал последние несколько лет. Описанное ниже - смесь из личного опыта, историй на различных форумах и анекдотов собранных через знакомых - поехали. Читать далее
Заметка о Mastodon — аналоге Twitter из вселенной децентрализованных соцсетей FediverseНа фоне текущих событий, когда уже привычным становится, что владельцы соцсетей своими собственными решениями блокируют отдельных пользователей (по их мнению, являющихся нехорошими), заинтересовался…
sysend.js is a library that allows a user to send messages between pages that are open in the same browser. Users that use cross-origin communication may have their communications intercepted. Impact is limited by the communication occurring in the same browser. This issue has been patched in sysend.js version 1.10.0. The only currently known workaround is to avoid sending communications that a user does not want to have intercepted via sysend messages.
Sylius is an open source eCommerce platform. In versions prior to 1.9.10, 1.10.11, and 1.11.2, it is possible to upload an SVG file containing cross-site scripting (XSS) code in the admin panel. In order to perform a XSS attack, the file itself has to be open in a new card or loaded outside of the IMG tag. The problem applies both to the files opened on the admin panel and shop pages. The issue is fixed in versions 1.9.10, 1.10.11, and 1.11.2. As a workaround, require a library that adds on-upload file…
Volto is a ReactJS-based frontend for the Plone Content Management System. Between versions 14.0.0-alpha.5 and 15.0.0-alpha.0, a user could have their authentication cookie replaced with an authentication cookie from another user, effectively giving them control of the other user's account and privileges. This occurs when using an outdated version of the `react-cookie` library and a server is under high load. A proof of concept does not currently exist, but it is possible for this issue to occur in the…
Heap out-of-bounds read in Clickhouse's LZ4 compression codec when parsing a malicious query. As part of the LZ4::decompressImpl() loop, a 16-bit unsigned user-supplied value ('offset') is read from the compressed data. The offset is later used in the length of a copy operation, without checking the upper bounds of the source of the copy operation.
