Description

A flaw was found in CUPS, an open-source printing system. An unprivileged local user can exploit an integer underflow vulnerability by providing a negative job-password-supported Internet Printing Protocol (IPP) attribute. This manipulation causes the cupsd root process to crash, which can be repeatedly triggered to achieve a sustained Denial of Service (DoS) on the system.
