CVE-2018-5159 – Skia and Firefox - Integer Overflow in SkTDArray Leading to Out-of-Bounds Write
https://notcve.org/view.php?id=CVE-2018-5159
An integer overflow can occur in the Skia library due to 32-bit integer use in an array without integer overflow checks, resulting in possible out-of-bounds writes. This could lead to a potentially exploitable crash triggerable by web content. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8. Puede ocurrir un desbordamiento de enteros en la biblioteca Skia debido al uso de números enteros de 32 bits en un array sin verificaciones de desbordamiento de enteros, resultando en posibles escrituras fuera de límites. Esto podría provocar un fallo potencialmente explotable desencadenable por el contenido web. • https://www.exploit-db.com/exploits/44759 http://www.securityfocus.com/bid/104136 http://www.securitytracker.com/id/1040896 https://access.redhat.com/errata/RHSA-2018:1414 https://access.redhat.com/errata/RHSA-2018:1415 https://access.redhat.com/errata/RHSA-2018:1725 https://access.redhat.com/errata/RHSA-2018:1726 https://bugzilla.mozilla.org/show_bug.cgi?id=1441941 https://lists.debian.org/debian-lts-announce/2018/05/msg00007.html https://lists.debian.org/debian-lts- • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
CVE-2018-5168 – Mozilla: Lightweight themes can be installed without user interaction
https://notcve.org/view.php?id=CVE-2018-5168
Sites can bypass security checks on permissions to install lightweight themes by manipulating the "baseURI" property of the theme element. This could allow a malicious site to install a theme without user interaction which could contain offensive or embarrassing images. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8. Los sitios pueden omitir las comprobaciones de seguridad de los permisos para instalar temas ligeros manipulando la propiedad "baseURI" del elemento theme. Esto podría permitir que un sitio malicioso instale un tema sin la interacción del usuario que podría contener imágenes ofensivas o embarazosas. • http://www.securityfocus.com/bid/104136 http://www.securitytracker.com/id/1040896 https://access.redhat.com/errata/RHSA-2018:1414 https://access.redhat.com/errata/RHSA-2018:1415 https://access.redhat.com/errata/RHSA-2018:1725 https://access.redhat.com/errata/RHSA-2018:1726 https://bugzilla.mozilla.org/show_bug.cgi?id=1449548 https://lists.debian.org/debian-lts-announce/2018/05/msg00007.html https://lists.debian.org/debian-lts-announce/2018/05/msg00013.html https://securi • CWE-862: Missing Authorization •
CVE-2018-5158 – pdf.js < 2.0.943 - Authenticated (Author+) Stored Cross-Site Scripting
https://notcve.org/view.php?id=CVE-2018-5158
The PDF viewer does not sufficiently sanitize PostScript calculator functions, allowing malicious JavaScript to be injected through a crafted PDF file. This JavaScript can then be run with the permissions of the PDF viewer by its worker. This vulnerability affects Firefox ESR < 52.8 and Firefox < 60. El visor de PDF no sanea suficientemente las funciones de la calculadora PostScript, lo que permite inyectar JavaScript malicioso a través de un archivo PDF manipulado. Este JavaScript puede ser ejecutado por su worker con los permisos del visor de PDF. • https://github.com/ppcrab/CVE-2018-5158 https://github.com/puzzle-tools/-CVE-2018-5158.pdf http://www.securityfocus.com/bid/104136 http://www.securitytracker.com/id/1040896 https://access.redhat.com/errata/RHSA-2018:1414 https://access.redhat.com/errata/RHSA-2018:1415 https://bugzilla.mozilla.org/show_bug.cgi?id=1452075 https://lists.debian.org/debian-lts-announce/2018/05/msg00007.html https://security.gentoo.org/glsa/201810-01 https://usn.ubuntu.com/3645-1 https& • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') •
CVE-2018-1087 – Kernel: KVM: error in exception handling leads to wrong debug stack value
https://notcve.org/view.php?id=CVE-2018-1087
kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and exceptions, rather they are delivered once the first instruction after the stack switch is executed. An unprivileged KVM guest user could use this flaw to crash the guest or, potentially, escalate their privileges in the guest. kernel KVM en versiones anteriores al kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 y kernel 4.17-rc3 es vulnerable a un error en la forma en la que el hipervisor KVM del kernel de Linux gestiona las excepciones lanzadas tras una operación de cambio de pila mediante instrucciones Mov SS o Pop SS. Durante la operación de cambio de pila, el procesador no lanzó interrupciones y excepciones, sino que las lanza una vez se ha ejecutado la primera instrucción tras el cambio de pila. Un usuario invitado sin privilegios de KVM podría usar este error para provocar el cierre inesperado del guest o escalar sus privilegios en el guest. • http://www.openwall.com/lists/oss-security/2018/05/08/5 http://www.securityfocus.com/bid/104127 http://www.securitytracker.com/id/1040862 https://access.redhat.com/errata/RHSA-2018:1318 https://access.redhat.com/errata/RHSA-2018:1345 https://access.redhat.com/errata/RHSA-2018:1347 https://access.redhat.com/errata/RHSA-2018:1348 https://access.redhat.com/errata/RHSA-2018:1355 https://access.redhat.com/errata/RHSA-2018:1524 https://access.redhat.com/security/vulnerabili • CWE-250: Execution with Unnecessary Privileges •
CVE-2018-1000199 – kernel: ptrace() incorrect error handling leads to corruption and DoS
https://notcve.org/view.php?id=CVE-2018-1000199
The Linux Kernel version 3.18 contains a dangerous feature vulnerability in modify_user_hw_breakpoint() that can result in crash and possibly memory corruption. This attack appear to be exploitable via local code execution and the ability to use ptrace. This vulnerability appears to have been fixed in git commit f67b15037a7a50c57f72e69a6d59941ad90a0f0f. El kernel de Linux en su versión 3.18 contiene una vulnerabilidad de funcionalidad peligrosa en modify_user_hw_breakpoint() que puede resultar en un cierre inesperado y en una posible corrupción de memoria. El ataque parece ser explotable mediante la ejecución de código local y la capacidad de usar ptrace. • https://github.com/dsfau/CVE-2018-1000199 http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://www.securitytracker.com/id/1040806 https://access.redhat.com/errata/RHSA-2018:1318 https://access.redhat.com/errata/RHSA-2018:1345 https://access.redhat.com/errata/RHSA-2018:1347 https://access.redhat.com/errata/RHSA-2018:1348 https://access.redhat.com/errata/RHSA-2018:1354 https://access.redhat.com/errata/RHSA-2018:1355 https://access.redhat.com/err • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-460: Improper Cleanup on Thrown Exception •
