Subject: [Buildroot] [PATCH 4/4 v2] package/cups-filters: bump to version 2.0.1
Date: Wed, 20 Aug 2025 18:39:21 +0200	[thread overview]
Message-ID: <20250820163921.1968030-5-angelo.compagnucci@gmail.com> (raw)
In-Reply-To: <20250820163921.1968030-1-angelo.compagnucci@gmail.com>

Changelog:
https://github.com/OpenPrinting/cups-filters/releases/tag/2.0.1

This version makes use of two ancillary libraries split from the main code.
Those libraries are:
* libcupsfilters
* libppd

This required a major rework of the package because most of the dependencies
were moved those new libraries.

-Subject: [PATCH] beh backend: Use execv() instead of system() - CVE-2023-24805
-
-With execv() command line arguments are passed as separate strings and
-not the full command line in a single string. This prevents arbitrary
-command execution by escaping the quoting of the arguments in a job
-with a forged job title.
-
-In addition, done the following fixes and improvements:
-
-- Do not allow '/' in the scheme of the URI (= backend executable
-  name), to assure that only backends inside /usr/lib/cups/backend/
-  are used.
-
-- URI must have ':', to split off scheme, otherwise error out.
-
-- Check return value of snprintf() to create call path for backend, to
-  error out on truncation of a too long scheme or on complete failure
-  due to a completely odd scheme.
-
-- Use strncat() instead of strncpy() for getting scheme from URI, the latter
-  does not require setting terminating zero byte in case of truncation.
-
-- Also exclude "." or ".." as scheme, as directories are not valid CUPS
-  backends.
-
-- Do not use fprintf() in sigterm_handler(), to not interfere with a
-  fprintf() which could be running in the main process when
-  sigterm_handler() is triggered.
-
-- Use "static volatile int" for global variable job_canceled.
-
