CVSS: 7.8EPSS: 0%CPEs: 16EXPL: 0CVE-2018-15911 – ghostscript: Uninitialized memory access in the aesdecode operator (699665)
https://notcve.org/view.php?id=CVE-2018-15911
In Artifex Ghostscript 9.23 before 2018-08-24, attackers able to supply crafted PostScript could use uninitialized memory access in the aesdecode operator to crash the interpreter or potentially execute code. En Artifex Ghostscript 9.23 antes del 24/08/2018, los atacantes que puedan proporcionar archivos PostScript manipulados podrían emplear un acceso a la memoria no inicializada en el operador aesdecode para provocar el cierre inesperado del intérprete o ejecutar código. It was discovered that ghostscript did not properly verify the key used in aesdecode. 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=8e9ce5016db968b40e4ec255a3005f2786cce45f http://www.securityfocus.com/bid/105122 https://access.redhat.com/errata/RHSA-2018:3834 https://bugs.ghostscript.com/show_bug.cgi?id=699665 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-456: Missing Initialization of a Variable CWE-908: Use of Uninitialized Resource •

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 •

A vulnerability was discovered in SPICE before version 0.14.1 where the generated code used for demarshalling messages lacked sufficient bounds checks. A malicious client or server, after authentication, could send specially crafted messages to its peer which would result in a crash or, potentially, other impacts. Se ha descubierto una vulnerabilidad en SPICE en versiones anteriores a la 0.14.1 en la que el código generado utilizado para deserializar mensajes carecía de comprobaciones de límites suficientes.

CVSS: 7.8EPSS: 1%CPEs: 152EXPL: 0CVE-2018-5391 – The Linux kernel, versions 3.9+, IP implementation is vulnerable to denial of service conditions with low rates of specially modified packets
https://notcve.org/view.php?id=CVE-2018-5391
The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size. El kernel de Linux en versiones a partir de la 3.9 es vulnerable a un ataque de denegación de servicio (DoS) con tasas bajas de paquetes especialmente modificados que apuntan hacia el reensamblado de fragmentos de IP. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200115-01-linux-en http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/105108 http://www.securitytracker.com/id/1041476 http://www.securitytracker.com/id/1041637 https://access.redhat.co • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
