https://notcve.org/view.php?id=CVE-2018-16863
It was found that RHSA-2018:2918 did not fully fix CVE-2018-16509. An attacker could possibly exploit another variant of the flaw and bypass the -dSAFER protection to, for example, execute arbitrary shell commands via a specially crafted PostScript document. This only affects ghostscript 9.07 as shipped with Red Hat Enterprise Linux 7. Se ha detectado que RHSA-2018:2918 no ha resuelto por completo CVE-2018-16509. Un atacante podría explotar otra variante del fallo y omitir la protección -dSAFER para, por ejemplo, ejecutar comandos de shell arbitrarios a través de un documento PostScript especialmente diseñado. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=520bb0ea7519 http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=5516c614dc33 http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=78911a01b67d http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=79cccf641486 https://access.redhat.com/errata/RHSA-2018:3761 https://bugzilla.redhat.com/show_bug.cgi? • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-184: Incomplete List of Disallowed Inputs •
