CVE-2019-6977 – PHP 7.2 - 'imagecolormatch()' Out of Band Heap Write
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 •
CVE-2019-3819
https://notcve.org/view.php?id=CVE-2019-3819
A flaw was found in the Linux kernel in the function hid_debug_events_read() in drivers/hid/hid-debug.c file which may enter an infinite loop with certain parameters passed from a userspace. A local privileged user ("root") can cause a system lock up and a denial of service. Versions from v4.18 and newer are vulnerable. Se ha detectado un fallo en el kernel de Linux, en la función hid_debug_events_read() en el archivo en drivers/hid/hid-debug.c, que podría entrar en un bucle infinito con determinados parámetros que se pasan desde un espacio de usuario. Un usuario local con privilegios ("root") puede causar el bloqueo del sistema y una denegación de servicio (DoS). • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00052.html http://www.securityfocus.com/bid/106730 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3819 https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html https://lists.debian.org/debian-lts-announce/2019/04/msg00004.html https://lists.debian.org/debian-lts-announce/2019/05/msg00002.html https://usn.ubuntu.com/3932-1 https://usn.ubuntu.com/3932-2 https://usn.ubuntu.com/4115-1 https: • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-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: •
CVE-2018-17189 – httpd: mod_http2: DoS via slow, unneeded request bodies
https://notcve.org/view.php?id=CVE-2018-17189
In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections. En Apache HTTP Server, en sus versiones 2.4.37 y anteriores, mediante el envío de cuerpos de respuesta mediante la técnica del "slow loris" a recursos planos, la transmisión h2 para esa petición ocupó de forma innecesaria un hilo de servidor que limpiaba tales datos entrantes. Esto afecta solo a las conexiones HTTP/2 (mod_http2). • http://www.securityfocus.com/bid/106685 https://access.redhat.com/errata/RHSA-2019:3932 https://access.redhat.com/errata/RHSA-2019:3933 https://access.redhat.com/errata/RHSA-2019:3935 https://access.redhat.com/errata/RHSA-2019:4126 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-17199 – httpd: mod_session_cookie does not respect expiry time
https://notcve.org/view.php?id=CVE-2018-17199
In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded. En Apache HTTP Server 2.4, en sus distribuciones 2.4.37 y anteriores, mod_session comprueba el tiempo de caducidad de la sesión antes de descodificarla. Esto provoca que se ignore el tiempo de caducidad de la sesión para sesiones mod_session_cookie, debido a que el tiempo de caducidad se carga cuando la sesión está descodificada. • http://www.securityfocus.com/bid/106742 https://access.redhat.com/errata/RHSA-2019:3932 https://access.redhat.com/errata/RHSA-2019:3933 https://access.redhat.com/errata/RHSA-2019:3935 https://access.redhat.com/errata/RHSA-2019:4126 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache • CWE-384: Session Fixation CWE-613: Insufficient Session Expiration •
