CVSS: 7.8EPSS: 0%CPEs: 11EXPL: 0CVE-2019-10216 – ghostscript: -dSAFER escape via .buildfont1 (701394)
https://notcve.org/view.php?id=CVE-2019-10216
In ghostscript before version 9.50, the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. An attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate privileges and access files outside of restricted areas. En ghostscript anterior a la versión 9.50, el procedimiento .buildfont1 no aseguraba adecuadamente sus llamadas privilegiadas, permitiendo que los scripts eludieran las restricciones `-dSAFER`. Un atacante podría abusar de esta fallo al crear un archivo PostScript especialmente diseñado que podría escalar privilegios y acceder a archivos fuera de las áreas restringidas. It was found that the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=5b85ddd19 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10216 https://security.gentoo.org/glsa/202004-03 https://access.redhat.com/security/cve/CVE-2019-10216 https://bugzilla.redhat.com/show_bug.cgi?id=1737080 • CWE-648: Incorrect Use of Privileged APIs •
