https://notcve.org/view.php?id=CVE-2020-15900
A memory corruption issue was found in Artifex Ghostscript 9.50 and 9.52. Use of a non-standard PostScript operator can allow overriding of file access controls. The 'rsearch' calculation for the 'post' size resulted in a size that was too large, and could underflow to max uint32_t. This was fixed in commit 5d499272b95a6b890a1397e11d20937de000d31b. Se encontró un problema de corrupción de memoria en Artifex Ghostscript versiones 9.50 y 9.52. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=log http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00006.html https://artifex.com/security-advisories/CVE-2020-15900 https://git.ghostscript.com/?p=ghostpdl.git%3Ba=commitdiff%3Bh=5d499272b95a6b890a1397e11d20937de000d31b https://github.com/ArtifexSoftware/ghostpdl/commit/5d499272b95a6b890a1397e11d20937de000d31b https://github.com/ArtifexSoftware/ghostpdl/commits/master/psi/zstring.c https: • CWE-191: Integer Underflow (Wrap or Wraparound) CWE-787: Out-of-bounds Write •

A flaw was found in all versions of ghostscript 9.x before 9.50, where the `.charkeys` procedure, where it 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 within the Ghostscript and access files outside of restricted areas or execute commands. Se detectó un fallo en todas las versiones de ghostscript 9.x en versiones anteriores a la 9.50, donde el procedimiento ".charkeys", donde no aseguraba apropiadamente sus llamadas privilegiadas, permitiendo que los scripts omitieran las restricciones "-dSAFER". Un atacante podría abusar de este fallo mediante la creación de un archivo PostScript especialmente diseñado que podría aumentar los privilegios dentro de Ghostscript y acceder a archivos fuera de áreas restringidas o ejecutar comandos.
