CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2018-15910 – ghostscript: LockDistillerParams type confusion (699656)
https://notcve.org/view.php?id=CVE-2018-15910
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use a type confusion in the LockDistillerParams parameter to crash the interpreter or execute code. En Artifex Ghostscript en versiones anteriores a la 9.24, los atacantes que puedan proporcionar archivos PostScript manipulados podrían emplear una confusión de tipos en el parámetro LockDistillerParams para provocar el cierre inesperado del intérprete o ejecutar código. It was discovered that the type of the LockDistillerParams parameter is not properly verified. 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=c3476dde7743761a4e1d39a631716199b696b880 http://www.securityfocus.com/bid/105122 https://access.redhat.com/errata/RHSA-2018:2918 https://bugs.ghostscript.com/show_bug.cgi?id=699656 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-704: Incorrect Type Conversion or Cast •

https://notcve.org/view.php?id=CVE-2018-10938
A flaw was found in the Linux kernel present since v4.0-rc1 and through v4.13-rc4. A crafted network packet sent remotely by an attacker may force the kernel to enter an infinite loop in the cipso_v4_optptr() function in net/ipv4/cipso_ipv4.c leading to a denial-of-service. A certain non-default configuration of LSM (Linux Security Module) and NetLabel should be set up on a system before an attacker could leverage this flaw. Se ha detectado un error en el kernel de Linux presente desde v4.0-rc1 y hasta v4.13-rc4. Un paquete de red manipulado enviado de forma remota por un atacante podría forzar al kernel a entrar en un bucle infinito en la función cipso_v4_optptr() en net/ipv4/cipso_ipv4.c, lo que conduce a una denegación de servicio (DoS). • http://seclists.org/oss-sec/2018/q3/179 http://www.securityfocus.com/bid/105154 http://www.securitytracker.com/id/1041569 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10938 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=40413955ee265a5e42f710940ec78f5450d49149 https://lists.debian.org/debian-lts-announce/2018/10/msg00003.html https://usn.ubuntu.com/3797-1 https://usn.ubuntu.com/3797-2 https://www.debian.org/security/2018/dsa-4308 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

https://notcve.org/view.php?id=CVE-2011-2767
mod_perl 2.0 through 2.0.10 allows attackers to execute arbitrary Perl code by placing it in a user-owned .htaccess file, because (contrary to the documentation) there is no configuration option that permits Perl code for the administrator's control of HTTP request processing without also permitting unprivileged users to run Perl code in the context of the user account that runs Apache HTTP Server processes. mod_perl 2.0 hasta la versión 2.0.10 permite que los atacantes ejecuten código Perl colocándolo en un archivo .htaccess propiedad del usuario, debido a que (al contrario de lo que pone en la documentación) no hay una opción de configuración que permita el código Perl para el control de administrador del procesamiento de peticiones HTTP sin permitir también que usuarios sin privilegios ejecuten código Perl en el contexto de la cuenta de usuario que ejecuta los procesos Apache HTTP Server. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00063.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00065.html http://www.securityfocus.com/bid/105195 https://access.redhat.com/errata/RHSA-2018:2737 https://access.redhat.com/errata/RHSA-2018:2825 https://access.redhat.com/errata/RHSA-2018:2826 https://bugs.debian.org/644169 https://lists.apache.org/thread.html/c8ebe8aad147a3ad2e7b0e8b2da45263171ab5d0fc7f8c100feaa94d%40%3Cmodperl-cvs.perl.apache.org%3E https://li • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-266: Incorrect Privilege Assignment •

Unchecked NULL pointer usage when handling invalid aliases in CopyKeyAliasesToKeymap in xkbcomp/keycodes.c in xkbcommon before 0.8.1 could be used by local attackers to crash (NULL pointer dereference) the xkbcommon parser by supplying a crafted keymap file. El uso de un puntero NULL no verificado al gestionar alias inválidos en CopyKeyAliasesToKeymap en xkbcomp/keycodes.c en xkbcommon, en versiones anteriores a la 0.8.1, podría ser aprovechado por atacantes locales para provocar el cierre inesperado (desreferencia de puntero NULL) del analizador xkbcommon proporcionando un archivo keymap manipulado. • https://github.com/xkbcommon/libxkbcommon/commit/badb428e63387140720f22486b3acbd3d738859f https://lists.freedesktop.org/archives/wayland-devel/2018-August/039232.html https://security.gentoo.org/glsa/201810-05 https://usn.ubuntu.com/3786-1 https://usn.ubuntu.com/3786-2 • CWE-476: NULL Pointer Dereference •

Endless recursion exists in xkbcomp/expr.c in xkbcommon and libxkbcommon before 0.8.1, which could be used by local attackers to crash xkbcommon users by supplying a crafted keymap file that triggers boolean negation. Existe recursión infinita en xkbcomp/expr.c en xkbcommon y libxkbcommon en versiones anteriores a la 0.8.1, lo que podría ser empleado por atacantes locales para provocar el cierre inesperado de usuarios xkbcommon proporcionando un archivo keymap manipulado que desencadena la negación booleana.
