https://notcve.org/view.php?id=CVE-2021-3781
A trivial sandbox (enabled with the `-dSAFER` option) escape flaw was found in the ghostscript interpreter by injecting a specially crafted pipe command. This flaw allows a specially crafted document to execute arbitrary commands on the system in the context of the ghostscript interpreter. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se ha encontrado un fallo de escape trivial del sandbox (habilitado con la opción "-dSAFER") en el intérprete de ghostscript al inyectar un comando de tubería especialmente diseñado. Este fallo permite que un documento especialmente diseñado ejecute comandos arbitrarios en el sistema en el contexto del intérprete ghostscript. • https://bugzilla.redhat.com/show_bug.cgi?id=2002271 https://ghostscript.com/CVE-2021-3781.html https://security.gentoo.org/glsa/202211-11 • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
