CVE-2016-9933 – gd: Stack overflow in gdImageFillToBorder on truecolor images

https://notcve.org/view.php?id=CVE-2016-9933

Stack consumption vulnerability in the gdImageFillToBorder function in gd.c in the GD Graphics Library (aka libgd) before 2.2.2, as used in PHP before 5.6.28 and 7.x before 7.0.13, allows remote attackers to cause a denial of service (segmentation violation) via a crafted imagefilltoborder call that triggers use of a negative color value. Vulnerabilidad de consumo de pila en la función gdImageFillToBorder en gd.c en la GD Graphics Library (también conocida como libgd) en versiones anteriores a 2.2.2, como se utiliza en PHP en versiones anteriores a 5.6.28 y 7.x en versiones anteriores a 7.0.13, permite a atacantes remotos provocar una denegación de servicio (violación de segmentación) a través de una llamada imagefilltoborder manipulada que desencadena el uso de un valor de color negativo. An infinite recursion flaw was found in the gdImageFillToBorder() function from the gd library; also used by PHP imagefilltoborder() function, when passing a negative integer as the color parameter, triggering a stack overflow. A remote attacker with ability to force a negative color identifier when calling the function could crash the PHP application, causing a Denial of Service. • http://lists.opensuse.org/opensuse-updates/2016-12/msg00133.html http://lists.opensuse.org/opensuse-updates/2016-12/msg00142.html http://lists.opensuse.org/opensuse-updates/2017-01/msg00002.html http://lists.opensuse.org/opensuse-updates/2017-01/msg00034.html http://lists.opensuse.org/opensuse-updates/2017-01/msg00054.html http://www.debian.org/security/2017/dsa-3751 http://www.openwall.com/lists/oss-security/2016/12/12/2 http://www.php.net/ChangeLog-5.php http://www.p • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

CVE-2016-7414 – php: Out of bounds heap read when verifying signature of zip phar in phar_parse_zipfile

https://notcve.org/view.php?id=CVE-2016-7414

The ZIP signature-verification feature in PHP before 5.6.26 and 7.x before 7.0.11 does not ensure that the uncompressed_filesize field is large enough, which allows remote attackers to cause a denial of service (out-of-bounds memory access) or possibly have unspecified other impact via a crafted PHAR archive, related to ext/phar/util.c and ext/phar/zip.c. La funcionalidad de verificación de firma ZIP en PHP en versiones anteriores a 5.6.26 y 7.x en versiones anteriores a 7.0.11 no asegura que el campo uncompressed_filesize sea suficientemente grande, lo que podría permitir a atacantes remotos provocar una denegación de servicio (acceso a memoria fuera de límites) o tener otro posible impacto no especificado a través de una archivo PHAR manipulado, relacionado con ext/phar/util.c y ext/phar/zip.c. • http://www.openwall.com/lists/oss-security/2016/09/15/10 http://www.php.net/ChangeLog-5.php http://www.php.net/ChangeLog-7.php http://www.securityfocus.com/bid/93004 http://www.securitytracker.com/id/1036836 https://access.redhat.com/errata/RHSA-2018:1296 https://bugs.php.net/bug.php?id=72928 https://github.com/php/php-src/commit/0bfb970f43acd1e81d11be1154805f86655f15d5?w=1 https://security.gentoo.org/glsa/201611-22 https://www.tenable.com/security/tns-2016-19 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
