CVE-2018-14624 – 389-ds-base: Server crash through modify command with large DN
https://notcve.org/view.php?id=CVE-2018-14624
A vulnerability was discovered in 389-ds-base through versions 1.3.7.10, 1.3.8.8 and 1.4.0.16. The lock controlling the error log was not correctly used when re-opening the log file in log__error_emergency(). An attacker could send a flood of modifications to a very large DN, which would cause slapd to crash. Se ha descubierto una vulnerabilidad en 389-ds-base hasta las versiones 1.3.7.10, 1.3.8.8 y 1.4.0.16. El bloqueo que controla el registro de errores no se empleaba correctamente al reabrir el archivo de registro en log__error_emergency(). • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00033.html https://access.redhat.com/errata/RHSA-2018:2757 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14624 https://lists.debian.org/debian-lts-announce/2018/09/msg00037.html https://pagure.io/389-ds-base/issue/49937 https://access.redhat.com/security/cve/CVE-2018-14624 https://bugzilla.redhat.com/show_bug.cgi?id=1619450 • CWE-20: Improper Input Validation •
CVE-2018-16542 – ghostscript: .definemodifiedfont memory corruption if /typecheck is handled (699668)
https://notcve.org/view.php?id=CVE-2018-16542
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use insufficient interpreter stack-size checking during error handling to crash the interpreter. En Artifex Ghostscript en versiones anteriores a la 9.24, los atacantes que puedan proporcionar archivos PostScript manipulados podrían emplear una comprobación insuficiente del tamaño de la pila del intérprete durante el manejo de errores para provocar el cierre inesperado del intérprete. It was discovered that ghostscript did not properly handle certain stack overflow error conditions. 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=b575e1ec42cc86f6a58c603f2a88fcc2af699cc8 http://seclists.org/oss-sec/2018/q3/182 http://www.securityfocus.com/bid/105337 https://access.redhat.com/errata/RHSA-2018:2918 https://bugs.ghostscript.com/show_bug.cgi?id=699668 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://acc • CWE-787: Out-of-bounds Write •
CVE-2018-16540 – ghostscript: use-after-free in copydevice handling (699661)
https://notcve.org/view.php?id=CVE-2018-16540
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files to the builtin PDF14 converter could use a use-after-free in copydevice handling to crash the interpreter or possibly have unspecified other impact. En Artifex Ghostscript en versiones anteriores a la 9.24, los atacantes que puedan proporcionar archivos PostScript manipulados al convertidor PDF14 integrado podrían emplear un uso de memoria previamente liberada en el manejo de copydevice para provocar el cierre inesperado del intérprete u otro tipo de impacto sin especificar. It was discovered that the ghostscript PDF14 compositor did not properly handle the copying of a device.

CVE-2018-16509 – Ghostscript - Failed Restore Command Execution
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".

CVE-2018-14622
https://notcve.org/view.php?id=CVE-2018-14622
A null-pointer dereference vulnerability was found in libtirpc before version 0.3.3-rc3. The return value of makefd_xprt() was not checked in all instances, which could lead to a crash when the server exhausted the maximum number of available file descriptors. A remote attacker could cause an rpc-based application to crash by flooding it with new connections. Se ha encontrado una vulnerabilidad de desreferencia de puntero NULL en libtirpc en versiones anteriores a la 0.3.3-rc3. El valor de retorno de makefd_xprt() no se comprobó en todas las instancias, lo que podría conducir a un cierre inesperado cuando el servidor agotó el número máximo de descriptores de archivo disponibles. • http://git.linux-nfs.org/?p=steved/libtirpc.git%3Ba=commit%3Bh=1c77f7a869bdea2a34799d774460d1f9983d45f0 https://access.redhat.com/errata/RHBA-2017:1991 https://bugzilla.novell.com/show_bug.cgi?id=968175 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14622 https://lists.debian.org/debian-lts-announce/2018/08/msg00034.html https://usn.ubuntu.com/3759-1 https://usn.ubuntu.com/3759-2 • CWE-252: Unchecked Return Value •
