CVSS: 6.1EPSS: 0%CPEs: 29EXPL: 0CVE-2018-18506 – Mozilla: Proxy Auto-Configuration file can define localhost access to be proxied
https://notcve.org/view.php?id=CVE-2018-18506
When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing. This vulnerability affects Firefox < 65. Cuando la autodetección del proxy está habilitada, si un servidor web proporciona un archivo de autoconfiguración de proxy (PAC) o si dicho archivo se carga localmente, este último puede especificar peticiones al host local que están destinadas a enviarse a través del proxy hacia otro servidor. Este comportamiento está prohibido por defecto cuando un proxy se configura manualmente. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00043.html http://www.securityfocus.com/bid/106773 https://access.redhat.com/errata/RHSA-2019:0622 https://access.redhat.com/errata/RHSA-2019:0623 https://access.redhat.com/errata/RHSA-2019:0680 https:/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2018-18500
A use-after-free vulnerability can occur while parsing an HTML5 stream in concert with custom HTML elements. This results in the stream parser object being freed while still in use, leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65. Una vulnerabilidad de memoria previamente liberada puede ocurrir a la hora de analizar una transmisión HTML5 junto con elementos HTML personalizados. Esto resulta en la liberación del objeto de análisis de transmisión mientras está en uso, conduciendo potencialmente a un cierre inesperado explotable. • https://github.com/sophoslabs/CVE-2018-18500 http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00021.html http://www.securityfocus.com/bid/106781 https://access.redhat.com/errata/RHSA-2019:0218 https://access.redhat.com/errata/RHSA-2019:0219 https://access.redhat.com/errata/RHSA-2019:0269 https://access.redhat.com/errata/RHSA-2019:0270 https://lists.debian.org/debian-lts-announce/2019/01/msg00025.html https://lists.debian.org/debian-lts-announce/2019/02/msg00024 • CWE-416: Use After Free •
CVSS: 10.0EPSS: 0%CPEs: 18EXPL: 0CVE-2018-18505 – Mozilla: Privilege escalation through IPC channel messages
https://notcve.org/view.php?id=CVE-2018-18505
An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65. Una solución anterior para la vulnerabilidad de comunicación entre procesos (IPC), CVE-2011-3079, añadía una autenticación para comunicaciones entre endpoints de IPC y servidores padres durante la creación de procesos IPC. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00021.html http://www.securityfocus.com/bid/106781 https://access.redhat.com/errata/RHSA-2019:0218 https://access.redhat.com/errata/RHSA-2019:0219 https://access.redhat.com/errata/RHSA-2019:0269 https://access.redhat.com/errata/RHSA-2019:0270 https://bugzilla.mozilla.org/show_bug.cgi?id=1087565 https://lists.debian.org/debian-lts-announce/2019/01/msg00025.html https://lists.debian.org/debian-lts-announce/2019/02&# • CWE-287: Improper Authentication •

https://notcve.org/view.php?id=CVE-2019-3813
Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-bounds read due to an off-by-one error in memslot_get_virt. This may lead to a denial of service, or, in the worst case, code-execution by unauthenticated attackers. Spice, desde la versión 0.5.2 hasta la 0.14.1, son vulnerables a una lectura fuera de límites debido a un error por un paso en memslot_get_virt. Esto podría conducir a una denegación de servicio (DoS) o, en el peor de los casos, la ejecución de código por parte de atacantes no autenticados. • http://www.securityfocus.com/bid/106801 https://access.redhat.com/errata/RHSA-2019:0231 https://access.redhat.com/errata/RHSA-2019:0232 https://access.redhat.com/errata/RHSA-2019:0457 https://bugzilla.redhat.com/show_bug.cgi?id=1665371 https://lists.debian.org/debian-lts-announce/2019/01/msg00026.html https://security.gentoo.org/glsa/202007-30 https://usn.ubuntu.com/3870-1 https://www.debian.org/security/2019/dsa-4375 https://access.redhat.com/security/cve/CVE-2 • CWE-193: Off-by-one Error •
CVSS: 7.8EPSS: 2%CPEs: 18EXPL: 4CVE-2019-6116 – Ghostscript 9.26 - Pseudo-Operator Remote Code Execution
https://notcve.org/view.php?id=CVE-2019-6116
In Artifex Ghostscript through 9.26, ephemeral or transient procedures can allow access to system operators, leading to remote code execution. En Artifex Ghostscript hasta la versión 9.26, los procedimientos ephemeral o transient pueden permitir el acceso a los operadores del sistema, lo que conduce a la ejecución remota de código. It was found that ghostscript could leak sensitive operators on the operand stack when a pseudo-operator pushes a subroutine. A specially crafted PostScript file could use this flaw to escape the -dSAFER protection in order to, for example, have access to the file system outside of the SAFER constraints. Ghostscript has an issue with pseudo-operators that can lead to remote code execution. • https://www.exploit-db.com/exploits/46242 http://lists.opensuse.org/opensuse-security-announce/2019-01/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-01/msg00048.html http://packetstormsecurity.com/files/151307/Ghostscript-Pseudo-Operator-Remote-Code-Execution.html http://packetstormsecurity.com/files/152367/Slackware-Security-Advisory-ghostscript-Updates.html http://www.openwall.com/lists/oss-security/2019/01/23/5 http://www.openwall.com/lists/oss-security/2019/03/21/1 http: •
