Artifex Ghostscript before 9.53.0 has an out-of-bounds write and use-after-free in devices/vector/gdevtxtw.c (for txtwrite) because a single character code in a PDF document can map to more than one Unicode code point (e.g., for a ligature). Artifex Ghostscript anterior a 9.53.0 tiene una escritura y un use-after-free fuera de los límites en devices/vector/gdevtxtw.c (para txtwrite) porque un código de un solo carácter en un documento PDF se puede asignar a más de un punto de código Unicode. (por ejemplo, para una ligadura). • https://bugs.ghostscript.com/show_bug.cgi?id=702229 https://bugzilla.opensuse.org/show_bug.cgi?id=1177922 https://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=8c7bd787defa071c96289b7da9397f673fddb874 https://github.com/ArtifexSoftware/ghostpdl-downloads/releases/tag/gs9530 • CWE-416: Use After Free CWE-787: Out-of-bounds Write •

CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 1CVE-2023-43115 – Ghostscript: GhostPDL can lead to remote code execution via crafted PostScript documents
https://notcve.org/view.php?id=CVE-2023-43115
In Artifex Ghostscript through 10.01.2, gdevijs.c in GhostPDL can lead to remote code execution via crafted PostScript documents because they can switch to the IJS device, or change the IjsServer parameter, after SAFER has been activated. NOTE: it is a documented risk that the IJS server can be specified on a gs command line (the IJS device inherently must execute a command to start the IJS server). En Artifex Ghostscript hasta 10.01.2, gdevijs.c en GhostPDL puede conducir a la ejecución remota de código a través de documentos PostScript manipulados porque pueden cambiar al dispositivo IJS, o cambiar el parámetro IjsServer, después de que se haya activado SAFER. NOTA: es un riesgo documentado que el servidor IJS se pueda especificar en una línea de comandos gs (el dispositivo IJS debe ejecutar inherentemente un comando para iniciar el servidor IJS). A vulnerability was found in Artifex Ghostscript in gdevijs.c, allows a malicious remote attacker to perform remote code execution via crafted PostScript documents. • https://github.com/jostaub/ghostscript-CVE-2023-43115 https://bugs.ghostscript.com/show_bug.cgi?id=707051 https://ghostscript.com https://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=e59216049cac290fb437a04c4f41ea46826cfba5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IK3UXJ5HKMPAL5EQELJAWSRPA2AUOJJO https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PG5AQV7JOL5TAU76FWPJCMSKO5DREKV5 https://access.redhat.com/security/cve/CVE-2023-43115 h • CWE-94: Improper Control of Generation of Code ('Code Injection') •
