https://notcve.org/view.php?id=CVE-2018-16509
An issue was discovered in Artifex Ghostscript before 9.24. Incorrect "restoration of privilege" checking during handling of /invalidaccess exceptions could be used by attackers able to supply crafted PostScript to execute code using the "pipe" instruction. Se ha descubierto un problema en versiones anteriores a la 9.24 de Artifex Ghostscript. La comprobación incorrecta de "restoration of privilege" durante el manejo de excepciones /invalidaccess podría ser empleada por atacantes que sean capaces de proporcionar PostScript manipulado para ejecutar código mediante la instrucción "pipe". It was discovered that the ghostscript /invalidaccess checks fail under certain conditions. • https://www.exploit-db.com/exploits/45369 https://github.com/farisv/PIL-RCE-Ghostscript-CVE-2018-16509 https://github.com/knqyf263/CVE-2018-16509 https://github.com/rhpco/CVE-2018-16509 http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=5516c614dc33662a2afdc377159f70218e67bde5 http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=78911a01b67d590b4a91afac2e8417360b934156 http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=79cccf641486a6595c43f1de1cd7ade696020a31 http://git.ghostscript.com/?p=gho •

https://notcve.org/view.php?id=CVE-2018-10911
A flaw was found in the way dic_unserialize function of glusterfs does not handle negative key length values. An attacker could use this flaw to read memory from other locations into the stored dict value. Se ha detectado un error en la forma en la que la función dic_unserialize en glusterfs no gestiona los valores de longitud de clave negativos. Un atacante podría utilizar este error para leer la memoria de otras ubicaciones en el valor dict almacenado. A flaw was found in dict.c:dict_unserialize function of glusterfs, dic_unserialize function does not handle negative key length values. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00035.html https://access.redhat.com/errata/RHSA-2018:2607 https://access.redhat.com/errata/RHSA-2018:2608 https://access.redhat.com/errata/RHSA-2018:2892 https://access.redhat.com/errata/RHSA-2018:3242 https://access.redhat.com/errata/RHSA-2018:3470 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10911 https://lists.debian.org/debian-lts-announce/2018/09/msg00021.html https://lists.debian.org/debian-lts • CWE-190: Integer Overflow or Wraparound CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-502: Deserialization of Untrusted Data •
