CVE-2023-24805

This project provides backends, filters, and other software that was once part of the core CUPS distribution but is no longer maintained by Apple Inc. In addition it contains additional filters and software developed independently of Apple, especially filters for the PDF-centric printing workflow introduced by OpenPrinting and a daemon to browse Bonjour broadcasts of remote CUPS printers to make these printers available locally and to provide backward compatibility to the old CUPS broadcasting and browsing of CUPS 1.5.x and older.

Security Fix(es):

cups-filters contains backends, filters, and other software required to get the cups printing service working on operating systems other than macos. If you use the Backend Error Handler (beh) to create an accessible network printer, this security vulnerability can cause remote code execution. beh.c contains the line retval = system(cmdline) >> 8; which calls the system command with the operand cmdline. cmdline contains multiple user controlled, unsanitized values. As a result an attacker with network access to the hosted print server can exploit this vulnerability to inject system commands which are executed in the context of the running server. This issue has been addressed in commit 8f2740357 and is expected to be bundled in the next release. Users are advised to upgrade when possible and to restrict access to network printers in the meantime.(CVE-2023-24805)

The cups-filters package contains back ends, filters, and other software that was once part of the core Common UNIX Printing System (CUPS) distribution but is now maintained independently.

Possible command injection in the Backend Error Handler (CVE-2023-24805)

These are all security issues fixed in the cups-filters-1.28.15-3.1 package on the GA media of openSUSE Tumbleweed.

This update for cups-filters fixes the following issues:

• CVE-2023-24805: Fixed a remote code execution in the beh backend (bsc#1211340).

This update for cups-filters fixes the following issues:

• CVE-2023-24805: Fixed a remote code execution in the beh backend (bsc#1211340).

This update for cups-filters, poppler, texlive fixes the following issues:

cups-filters:

• CVE-2023-24805: Fixed a remote code execution in the beh backend (bsc#1211340).

texlive:

• CVE-2023-32700: Fixed arbitrary code execution in LuaTeX (bsc#1211389).

poppler:

• Added missing header file goo/GooCheckedOps.h. Without it, other packages using poppler as a library might fail to compile since our public headers now depend on it. (bsc#1211450)

It was discovered that cups-filters incorrectly handled the beh CUPS backend. A remote attacker could possibly use this issue to cause the backend to stop responding or to execute arbitrary code.

USN-6083-1 fixed a vulnerability in cups-filters. This update provides the corresponding update for Ubuntu 16.04 LTS.

Original advisory details:

It was discovered that cups-filters incorrectly handled the beh CUPS backend. A remote attacker could possibly use this issue to cause the backend to stop responding or to execute arbitrary code.
