CVSS: 9.8EPSS: 22%CPEs: 18EXPL: 1CVE-2018-18500 – Mozilla: Use-after-free parsing HTML5 stream
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 •

https://notcve.org/view.php?id=CVE-2019-6977
gdImageColorMatch in gd_color_match.c in the GD Graphics Library (aka LibGD) 2.2.5, as used in the imagecolormatch function in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1, has a heap-based buffer overflow. This can be exploited by an attacker who is able to trigger imagecolormatch calls with crafted image data. gdImageColorMatch in gd_color_match.c en la versión 2.2.5 de GD Graphics Library (también conocido como LibGD), tal y como se utiliza en la función imagecolormatch en PHP, en versiones anteriores a la 5.6.40, en las 7.x anteriores a la 7.1.26, en las 7.2.x anteriores a la 7.2.14 y en las 7.3.x anteriores a la 7.3.1, tiene un desbordamiento de búfer basado en memoria dinámica (heap). Esto puede ser explotado por un atacante capaz de provocar llamadas imagecolormatch con datos de imagen manipulados. PHP version 7.2 suffers from an imagecolormatch() out-of-band heap write vulnerability. • https://www.exploit-db.com/exploits/46677 http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00031.html http://packetstormsecurity.com/files/152459/PHP-7.2-imagecolormatch-Out-Of-Band-Heap-Write.html http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://www.securityfocus.com/bid/106731 https://access.redhat.com/errata/RHSA-2019:2519 https://access.redhat.com/errata/RHSA-2019:32 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
