CVSS: 8.8EPSS: 71%CPEs: 12EXPL: 2CVE-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 •

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.

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: •
