CVSS: 5.5EPSS: 0%CPEs: 9EXPL: 2CVE-2018-5711 – gd: Infinite loop in gdImageCreateFromGifCtx() in gd_gif_in.c
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') •
CVSS: 7.5EPSS: 0%CPEs: 8EXPL: 1CVE-2017-16642 – PHP 7.1.8 - Heap Buffer Overflow
https://notcve.org/view.php?id=CVE-2017-16642
In PHP before 5.6.32, 7.x before 7.0.25, and 7.1.x before 7.1.11, an error in the date extension's timelib_meridian handling of 'front of' and 'back of' directives could be used by attackers able to supply date strings to leak information from the interpreter, related to ext/date/lib/parse_date.c out-of-bounds reads affecting the php_parse_date function. NOTE: this is a different issue than CVE-2017-11145. En PHP, en versiones anteriores a la 5.6.32, versiones 7.x anteriores a la 7.0.25 y versiones 7.1.x anteriores a la 7.1.11, un error en la manipulación de timelib_meridian de la extensión de fecha de las directivas "front of" y "back of" podría ser empleado por atacantes capaces de proporcionar cadenas de fechas para filtrar información del intérprete. Esto está relacionado con lecturas fuera de límites de ext/date/lib/parse_date.c que afectan a la función php_parse_date.

The secureCompare method in lib/SimpleSAML/Utils/Crypto.php in SimpleSAMLphp 1.14.13 and earlier, when used with PHP before 5.6, allows attackers to conduct session fixation attacks or possibly bypass authentication by leveraging missing character conversions before an XOR operation. El método secureCompare en lib/SimpleSAML/Utils/Crypto.php en SimpleSAMLphp 1.14.13 y anteriores, al usarse con PHP en versiones anteriores a la 5.6, permite que los atacantes lleven a cabo ataques de fijación de sesión o que, posiblemente, omitan la autenticación aprovechando las conversiones de caracteres que faltan antes de una operación XOR. • https://github.com/simplesamlphp/simplesamlphp/commit/4bc629658e7b7d17c9ac3fe0da7dc5df71f1b85e https://lists.debian.org/debian-lts-announce/2017/12/msg00007.html https://lists.debian.org/debian-lts-announce/2018/06/msg00017.html https://simplesamlphp.org/security/201705-01 • CWE-384: Session Fixation •

https://notcve.org/view.php?id=CVE-2017-7890
The GIF decoding function gdImageCreateFromGifCtx in gd_gif_in.c in the GD Graphics Library (aka libgd), as used in PHP before 5.6.31 and 7.x before 7.1.7, does not zero colorMap arrays before use. A specially crafted GIF image could use the uninitialized tables to read ~700 bytes from the top of the stack, potentially disclosing sensitive information. La función de descodificación de GIF "gdImageCreateFromGifCtx " en gd_gif_in.c en GD Graphics Library (también conocido como libgd),que se usa en PHP en versiones anteriores a la 5.6.31 y en todas las 7.x anteriores a la 7.1.7, no asigna el valor cero a los objetos array colorMap antes de usarse. Una imagen GIF especialmente manipulada podría utilizar las tablas no inicializadas para leer sobre 700 bytes por encima de la pila, pudiendo divulgar información sensible. A data leak was found in gdImageCreateFromGifCtx() in GD Graphics Library used in PHP before 5.6.31 and 7.1.7. • http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://www.debian.org/security/2017/dsa-3938 http://www.securityfocus.com/bid/99492 https://access.redhat.com/errata/RHSA-2018:0406 https://access.redhat.com/errata/RHSA-2018:1296 https://bugs.php.net/bug.php?id=74435 https://bugs.php.net/patch-display.php?bug=74435&patch=fix-74435-php-7.0&revision=1497970038 https://security.netapp.com/advisory/ntap-20180112-0001 https://www.tenable.com/security/t • CWE-20: Improper Input Validation CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
