Описание
Уязвимость демона cupsd сервера печати CUPS связана с недостатками механизма проверки входных данных при обработке параметра textWithoutLanguage. Эксплуатация уязвимости может позволить нарушителю, действующему удаленно, выполнить произвольный код путем отправки специально сформированного файла в очередь печати PostScript при помощи запроса Print-Job

OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, in a network-exposed cupsd with a shared target queue, an unauthorized client can send a Print-Job to that shared PostScript queue without authentication. The server accepts a page-border value supplied as textWithoutLanguage, preserves an embedded newline through option escaping and reparse, and then reparses the resulting second-line PPD: text as a trusted scheduler control record. A follow-up raw print job can therefore make the server execute an attacker-chosen existing binary such as /usr/bin/vim as lp. At time of publication, there are no publicly available patches.
