https://notcve.org/view.php?id=CVE-2018-15908
In Artifex Ghostscript 9.23 before 2018-08-23, attackers are able to supply malicious PostScript files to bypass .tempfile restrictions and write files. En Artifex Ghostscript 9.23 antes del 23/08/2018, los atacantes pueden proporcionar archivos PostScript maliciosos para omitir las restricciones .tempfile y escribir en archivos. It was discovered that the ghostscript .tempfile function did not properly handle file permissions. An attacker could possibly exploit this to exploit this to bypass the -dSAFER protection and delete files or disclose their content via a specially crafted PostScript document. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=0d3901189f245232f0161addf215d7268c4d05a3 https://access.redhat.com/errata/RHSA-2018:3650 https://lists.debian.org/debian-lts-announce/2018/09/msg00015.html https://security.gentoo.org/glsa/201811-12 https://usn.ubuntu.com/3768-1 https://www.debian.org/security/2018/dsa-4288 https://www.kb.cert.org/vuls/id/332928 https://access.redhat.com/security/cve/CVE-2018-15908 https://bugzilla.redhat.com/show_bug.cgi?id=1619756 •
CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2018-15910 – ghostscript: LockDistillerParams type confusion (699656)
https://notcve.org/view.php?id=CVE-2018-15910
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use a type confusion in the LockDistillerParams parameter to crash the interpreter or execute code. En Artifex Ghostscript en versiones anteriores a la 9.24, los atacantes que puedan proporcionar archivos PostScript manipulados podrían emplear una confusión de tipos en el parámetro LockDistillerParams para provocar el cierre inesperado del intérprete o ejecutar código. It was discovered that the type of the LockDistillerParams parameter is not properly verified. An attacker could possibly exploit this to bypass the -dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript document. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=c3476dde7743761a4e1d39a631716199b696b880 http://www.securityfocus.com/bid/105122 https://access.redhat.com/errata/RHSA-2018:2918 https://bugs.ghostscript.com/show_bug.cgi?id=699656 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44101 https://lists.debian.org/debian-lts-announce/2018/09/msg00015.html https://security.gentoo.org/glsa/201811-12 https://support.f5.com/csp/article/K22141757?utm_source=f5support&%3Butm_medium= • CWE-704: Incorrect Type Conversion or Cast •
