https://notcve.org/view.php?id=CVE-2018-5711
gd_gif_in.c in the GD Graphics Library (aka libgd), as used in PHP before 5.6.33, 7.0.x before 7.0.27, 7.1.x before 7.1.13, and 7.2.x before 7.2.1, has an integer signedness error that leads to an infinite loop via a crafted GIF file, as demonstrated by a call to the imagecreatefromgif or imagecreatefromstring PHP function. This is related to GetCode_ and gdImageCreateFromGifCtx. gd_gif_in.c en GD Graphics Library (también conocida como libgd), tal y como se emplea en PHP en versiones anteriores a la 5.6.33, versiones 7.0.x anteriores a la 7.0.27, versiones 7.1.x anteriores a la 7.1.13 y versiones 7.2.x anteriores a la 7.2.1, tiene un error en la propiedad signedness de un número entero que conduce a un bucle infinito mediante un archivo GIF manipulado, tal y como demuestra una llamada a las funciones de PHP imagecreatefromgif o imagecreatefromstring. Esto se relaciona con GetCode_ y gdImageCreateFromGifCtx. • https://github.com/huzhenghui/Test-7-2-0-PHP-CVE-2018-5711 https://github.com/huzhenghui/Test-7-2-1-PHP-CVE-2018-5711 http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php https://access.redhat.com/errata/RHSA-2018:1296 https://access.redhat.com/errata/RHSA-2019:2519 https://bugs.php.net/bug.php?id=75571 https://lists.debian.org/debian-lts-announce/2018/01/msg00022.html https://lists.debian.org/debian-lts-announce/2019/01/msg00028.html https:/ • CWE-681: Incorrect Conversion between Numeric Types CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

The zend_string_extend function in Zend/zend_string.h in PHP through 7.1.5 does not prevent changes to string objects that result in a negative length, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact by leveraging a script's use of .= with a long string. La función zend_string_extend en el archivo Zend/zend_string.h en PHP hasta de la versión 7.1.5 no impide cambios en los objetos de cadena que resultan en una longitud negativa, lo que permite a los atacantes remotos causar una denegación de servicio (bloqueo de aplicación) o posiblemente tener otro impacto no especificado explotando el uso de scripts .= con una cadena larga. • http://www.securityfocus.com/bid/98518 https://bugs.php.net/bug.php?id=74577 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2015-0235
Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST." Desbordamiento de buffer basado en memoria dinámica en la función __nss_hostname_digits_dots en glibc 2.2, y otras versiones 2.x anteriores a 2.18, permite a atacantes dependientes de contexto ejecutar código arbitrario a través de vectores relacionados con la funciín (1) gethostbyname o (2) gethostbyname2, también conocido como 'GHOST.' A heap-based buffer overflow was found in glibc's __nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls. A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. The industrial managed switch series 852 from WAGO is affected by multiple vulnerabilities such as old software components embedded in the firmware. • https://www.exploit-db.com/exploits/35951 https://www.exploit-db.com/exploits/36421 https://github.com/aaronfay/CVE-2015-0235-test https://github.com/makelinux/CVE-2015-0235-workaround https://github.com/sUbc0ol/CVE-2015-0235 https://github.com/mikesplain/CVE-2015-0235-cookbook https://github.com/tobyzxj/CVE-2015-0235 https://github.com/adherzog/ansible-CVE-2015-0235-GHOST http://blogs.sophos.com/2015/01/29/sophos-products-and-the-ghost-vulnerability-affecting-linux http:/ • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
