CVE-2015-8560
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIncomplete blacklist vulnerability in util.c in foomatic-rip in cups-filters 1.0.42 before 1.4.0 and in foomatic-filters in Foomatic 4.0.x allows remote attackers to execute arbitrary commands via a ; (semicolon) character in a print job, a different vulnerability than CVE-2015-8327.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceIncomplete blacklist vulnerability in util.c within foomatic-rip (cups-filters) and foomatic-filters allows remote attackers to execute arbitrary commands through print jobs by injecting a semicolon (;) character, bypassing input validation.

It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed cups-filters versionRun 'dpkg -l cups-filters' on Debian/Ubuntu or 'rpm -q cups-filters' on RPM-based systems to list the installed package versionAffected if The version listed is between 1.0.42 and 1.0.53 inclusive
-
Identify installed foomatic-filters versionRun 'dpkg -l foomatic-filters' on Debian/Ubuntu or 'rpm -q foomatic-filters' on RPM-based systems to list the installed package versionAffected if The version listed is between 4.0.0 and 4.0.11 inclusive
-
Verify foomatic-rip is in useCheck if CUPS is running ('systemctl status cups' or 'service cups status') and examine printer configuration files in /etc/cups/ to confirm foomatic-rip is the filter being used for any configured printersAffected if CUPS is active and printers are configured to use foomatic-rip as the raster filter or rip handler
-
Confirm print job submission is accessibleCheck if the CUPS web interface is bound to network interfaces ('Listen' or 'Port' directives in /etc/cups/cupsd.conf) or if anonymous print access is permitted in /etc/cups/printers.confAffected if CUPS is listening on a network interface or allows print jobs from untrusted sources
You are affected if you have cups-filters versions 1.0.42-1.0.53 or foomatic-filters versions 4.0.0-4.0.11 installed with CUPS running and foomatic-rip actively handling print jobs from accessible sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to cups-filters 1.4.0+ or Foomatic 4.0.x patched versions; alternatively, isolate print services in a restricted network segment and disable unnecessary print job submission interfaces.
