Vulnerability in OPMS

Issue/Introduction

The security team has identified vulnerability in the OPMS container. 

Details below:

Component: Libcups2

Container: asm-pop-fpm

Resolution

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.

Mitigation
Do not expose the cupsd to the internet, including a shared PostScript queue. Enabling the PostScript queue would involve changing the default configuration.

we're not using the library to run a print server, it's not really affecting ASM
